Hey all,

just before the keyboard warriors start flaming, yes I have searched.

I have just gone to hell with my car. some of you might know that I have been trying to locate my stuttering problem for some time now.

I have just recently cleaned my AAC unit. changed back to hks pod filters. new spark plugs.

when i turned the car back on after being batery-less for about a week, the car went fine for around 10mins. The only thing that was weird in its good condition was that it was booting WAY to high, way above the stock boost, and i could hear the turbos going nutz with the spooling.

after the 10mins the car turned into a wrx/boxer engine. as soon as you give it gas in any gear, it goes boxer. when it idles it idles at 1050rpm, too high. the car will rev all the way out in neutral.

There is no black/blue/white smoke coming from my exhaust pipe.

if someone/anyone could give me a run down of things to check, i would much appreciate this. thank you.

have u pulled the plugs & checked if any have started to foul?

the rev limit hasnt been set extremely low has it?

the reason for it revving in neutral i would say would be the fact that its not under any load.

so when you say it goes into boxer mode, is the thing running rough or???

I would try a compression test next to eliminate that being the problem.

boxer mode.. it runs very rough. no power. but it will rev without limitation just very roughly.

comp test, will do when i get my hands on one of those things.

ill check the plugs now. the rev limiter has never been touched, stock gtr.

i have had the injectors cleaned only 2 weeks ago.

ok i played with it again. i didnt pull the plugs out to check which one was fouling... do that tomorrow.

but when i was playing with the AFM plug the car started dying and doing what it does when im on the road in gear, wrx'ing.

The plug on the back AFM is damaged, as in where it used to have the plastic extension to bundle the wires with, that has disappeared because it has been hitting the power steering pump reservoir. Each time you touch this plug the car goes funny and idles like a 5 cyl car.

BTW it is NOT the AFM, I have eliminated this with a working set of AFM from another R32 gtr.

Doesnt that tell you something?...........Youve found the problem yourself. The wiring to the AFM is dodgy and should be re-done. Of course the other AFMs will show no difference since youre only changing the meter and not the wiring. I had the same problem and bought a brand new plug from one of the sponsors on here and it fixed the problem.

you get a star next to your name! lol. nah thanks for your imput.. i sort of gathered that that could contribute to the problem, but didnt think it would be so easy to figure out. let hope that when i fix this problems will go away.

so do you remember where you bought the plug? =)

ok. im adding more to this saga.

the AFM seems to be okay after all this. check the plug wiring, checked the afm solder joints, so that part is good.

Now when I start the car it is permanently in WRX mode.

I re-checked the ignition loom and tested each cylinder for a rev drop. Number 4 seems to be the only one that doesnt respond to a rev drop. I pulled out the spark plugs and Number 4 seems to be fouling, full of black crap.

to make sure it wasnt the coil pack, i switched coil pack number 4 with coil pack number 2 and the problem still is at cylinder 4.

I checked all the wiring i could and I can only think of the ignition module.

BTW: I checked the ECU light and got an all clear from the codes.

what is going on boys and girls?!?!?!

i had the exact same problem when i changed my sparks.... the mechanic who changed them didnt clip the electrical clips properly when putting it all back together and it sounded like a rexy and used allot of fuel, poor power and the car was shaking alittle. I just upened the cover where the coilpacks sit under and checked them all. problem went away after i clipped everything properly.

that was my solution to something with the same sounding problem but yours is something alittle more harder than mine....

yeh thanks mate, it could well be the clips but ive been over those many many times. cheers.

keep em coming team!

sounds like its getting fuel but no spark.

I would reckon ignitor module related. Even if it is buggered it wont necessarily throw an ECU code.

PS have you checked compression on no 4?

yeh seems like no spark in number 4. i think it could be ignition module related as well. ah thanks for mentioning that it might not show up on the ECU codes.

I havent checked the compression of number 4. how do i get one of those done, is it pricey? would they check that on a dyno as well?

Buy a compression gauge, they arent expensive. You just crank the engine over with all plugs out and the gauge in each cylinder. One at a time of course. Should read 150-160 PSI if its pretty fresh or slightly lower if its got a few km's on it. You need to do this before anything else to rule out mechanical fault.

Deren

OMFG EVERYONE!!!!!!

THE GTR IS BACK!!!! THE POWER IS AMAZING! OMFG OMFG OMFG

I will write a post on my experience in the 1 year of no power.

THANK YOU TO ALL those patient guys/girls that gave input to the issues, your advices were well worth it and were not looked over.

A little word to tease all of you about the post i will write.... spark.

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

OOOT

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out.
