Hey guys just thought for any of you that have experienced something like this and couldnt find the problem here is something els for you to check over.

I dont get much time to drive or work on my car these days, most of the time its on a saturday. So being saturday yesterday i took it for a drive and for awhile now ive had a few issues while driving it and the problem seemed to be getting worse over time and i could only notice it little by little because of the time difference between drives. Any way half way to my destination i lost alot of power and the car kept stalling when my foot wasn't on the accelorator (and this is bad because half way through an intersection i would loose breaks and power steering lol slip it back into Neutral turn key and have to accelerate). Lucky for me I had a spare set of plugs sitting in my glove box from ages ago, i thought maybe i had lost a cylinder or something because of all the black smoke that was comming out (just a guess maybe unburnt fuel?). so i got to my brothers house and i asked him for his tool kit and i began changing my plugs 1 hour it took me, and then while putting every thing back together i noticed a crack on the pipe that runs across coil pack cover its quite fat and only goes from one inlet to one outlet directly on ither side of the coil pack cover. the crack was about 6 cm long from the beginning of the left and side all the way round to just past the first corner. lol me being the bush machanic i am i found a quick fix. some brown packing tape, taped the abolute sh!t out of it and put it back on. took the car for a drive and it drive like it was brand spanking new.

So if you have any thing like this, where your car is lacking power, is bellowing black smoke, missfiring, and stalling when your foot isn't on the accerlator, It might be something as simple as a vacuum leak. oh and before i forget my plugs still had great points on them but oh well.... if any one knows of the pipe im talking about please add a picture for me thanks in advance.

now that the problem is fixed id advise you to disconnect that battery, hold brake down to release all residue power, reset and drive.

Im in that habit of resetting the ecu for any minor change........

The fault you have described is over-fuelling due to a metered-air leak. It's what makes AFM cars run like shite with atmospheric BOV's fitted.

Even a loose oil dipstick will mess up the running of the engine.

Yep exactly.

Damn afms, the amount times at drift days ive popped an intercooler hose and had to limp into the pits bellowing black smoke and barely running.

Got 3-4 hours drifting with 100mph tape on intercooler piping after it split, works a treat :blink:

And yeah my stagea drops on idle if you take the oil cap off.

dunno about resetting the ecu brother ive got a Greddy emanage ultimate.... what will happen if the ecu is reset? isnt the Greddy a piggy back system and alters the air fuel and ignition according to what its fed from the stock ecu? im no guru but i dunno what will happen. Will it reset my Greddy? so many unknowns lol.

I dont think it will reset the emananage, these normally have to be reset via the software. What it does is resets any fault codes the computer has registered. So if its in say limp home mode it will reset from this and go back to normal. I had to do this to correct my idle with the stock 26 ecu after we fixed a few vaccum leaks.

    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
