Hi hows it going,
I currently have a Nissan Skyline r33 Series 2 gts-t, its got a few issues with it currently, it currently has a Front Mount Inter cooler, used to have a HKS Blow Off Valve but replaced it with the stock one. It has a 3" Full Exhaust, as well it has a Automatic boost controller however its got the display sort of smashed, so going to replace it soon with a manual one it as well has a turbo timer.
One of the issues is that its blowing black smoke and there and its leaking the black stuff from the exhaust onto the floor, also there is sense of a strong smell of petrol. My assumption its running quite rich, so im guessing could it be due for a tune, or it might be running too much boost but ive reved it ideling and it has been showing the 7 pound of boost. The car is currently unregestired however its never been driven, so dont if reving the car shows its real boost.
My 2nd question is, the oil is pretty much black, so would that mean its time for a oil change and oil filter change.
My 3rd question, is when sometimes its ideling it turns it self off so i was wondering could this be miss fires, or is it just due for a tune. Because im thinking maybe i need to replace the spark plugs. Also when its been slightly reved on a warm engine, sometimes it will shut off and wont turn back on until you give it about 5mins and it will start right back up. If i start it up straight after it will struggle to start up sort of like an old car.
If you could help me, it will be greatly appreciated.
Yours Truly,
