problem been discussed a lot on sau, its common on all r32's to need a blip of the throttle to stop it stalling.

Unfortunately no one has found a solution to this problem :D

When i put in a brand new heavy duty battery it would crank and idle with no throttle, but over the weeks it went back to its stalling.

A possibly solution is to clean the cold air regulator which lets in more air on cold starts. Perhaps this could be getting stuck and causing the stalling;

Also doesnt hurt to clean the AAC valve too;

ive cleaned the AAC and AFM , there is a noticeable difference after cleaning it. if you haven't do so , i highly suggest you to do that first.

wanna do mine? <3 :)

How is your battery? You might have a weak battery, try recharging overnight and see how it goes.

When i put in a brand new battery it cranked once and jumped to life, but now its gone away :)

Also, when i first purchased the car it had no cold-start issues, it gradually happened after driving the car, so something must have worn out/clogged up during that time..

notice something funny, if i prime the fuel pump before cracking the engine, it most likely gonna have a hard cold start (rev below 700rpm)

HOWEVER, if i start the key straight away without waiting, the car actually starts at first go (rev stays at 7-800rpm bout 1-2 sec and its back to normal 1100-1200 rpm)

but still a tiny bit hesitation but no where near as bad as before.

Mine starts strangely in the morning also, turn the key and it fires up nicely. Revs drop to almost a stall, tap the throttle and up it goes to about 2 grand for a while. Strange yes! Done anything about it, no! :D

Here's a video of my starting which i recorded over a year ago. Sounds similar to yours AdMan

I always have to blip the throttle when starting or it stalls, i tend to blip the throttle into any other car i jump into because of this haha

Im putting in cleaned gtr injectors soon and getting a tune, will see if it will fix the problem.

Also, not sure if it helps, but after i installed a gtr fuel pump, the cold start actually got worse..ho hum

Definately clean your cold air regulator. It's a bit of a bitch to get to but it worked for me.

Had the same cold start problem as you. Turns out the regulator was stuck open, pulled it out and cleaned it and now it starts nicely - no throttle needed.

Hi there, I have had this issue for years now, I had the injectors cleaned, new temp sensor, cleaned the AAC valve and really didn't see that much of difference. One thing I did change which helped a lot was one of the Fuses that goes to the ECU, this made the most noticeable difference but didn't cure the issue. Does anyone have pics of what the Cold Air Reg looks like on a 33? Just want to have a look because it might be worth a crack.

Check out this thread for some pics of the cold air reg: http://www.skylinesaustralia.com/forums/Fi...ob-t174735.html

Seems like it's even harder to get at than in the RB20...

    • 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. 
    • Wife and I are still looking for a new home. One condition was a large enough garage for a full-size lift in one bay. Now if only we could find something... We've been looking for almost a year now.
    • Thanks everyone for the ideas! Sadly, ramps are a no go for me. With young kids at home, I do most of my work late at night while they're sleeping. Starting the car multiple times wouldn't be a great idea.  I'll go see one of those new long reach low profile jacks and take a couple measurements to see if they will fit.
