Last week I was driving my r33 gtst and suddenly the car stalled, when I tried starting it again the idle was all over the place and black smoke was coming from the exhaust.

I've had a look and play with it and have swapped the spark plugs out with (bcpre6s-11) or what ever they are and re gapped them to 0.8.

Once i put them in The car started and idle was hunting, I didn't drive the car.

The next morning I went to start it and it fires up then dies straight away, black carbon and oil is coming from the exhaust.

I've replaced the afm, plugs and had the injectors looked at and passed.

I have a few mods

Intercooler, air pod, forward facing plenum (not greddy) :/

Walbro fuel pump, super spark coilpacks, toshi ecu, has ssqv bov.

Has this happend to anyone?

Looking at them does cut it if its just popped a hose...

Sort of.

The amount of times people check for leaks visually, are adamant there are no leaks, only to eventually do a pressure test and find heaps of leaks is more than you think.

I just had a look under the bonnet and just sprayed a little bit of start ya barsted.

It started and stayed running, running very rich though. It sounds like it missing really bad instead of hunting for an idle.

Fuel pump is working fine too.

get a baked bean can. disconnect your intake pipe(the one that goes into the front of the turbo to the air flow meter) from the air flow meter and hose clamp the baked bean can into it tightly where the airflow meter used to connect... now unplug your line that goes from your intake pipe to your boost solenoid. grab some other hose that will fit on there and make it fit with some brass fitting or similar to a air compressor tyre pump...good idea to make sure it has a gauge on it. Then put a brick on the gas pedal.....then slowly put air into the intake....don't go too fast....if the pressure is dropping on the gauge quickly then you should hear it hissing.....this will be the first obvious leak....once you've tightened that....then start again....don't go over 1 bar of pressure in the intake otherwise you can risk injuring yourself like i nearly did when i pressurized it up to 2 bar and shot the baked bean can out.....if you don't have and air compressor then use a bike pump....might take longer though ;)

You don't need to open the throttle, air will make it's way into the plenum easily with that much pressure behind it.

Agreed, baked bean cans aren't the smartest option due to not having much of a lip. They can shoot out at high speed with even low pressure and do damage. I spun my 80mm bung up out of solid alloy and machined a generous lip on it so the clamp wouldn't let go. I have used it up to 40-50psi without a problem.

If you can't find something suitable there are other options, a few people sell pressure testers on ebay, or I could make you one if you don't have a machinist locally.

yeah I only used a baked bean can because it was all I had on hand the time. a proper tool for a proper job is always preferred.

    • 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.
