running rich!!!!!

[bonestocksr20]

Well me and my friend were going down the interstate and when i would gun my car gray smoke would come out. When we got to my house we let it idle for 5min and the i quickly reved it up. The exhaust smelled like raw fuel? So i took the ecu out and it read a code 55 which is normal. Any ideas of thing to check. Please help

Burning coolant causes white smoke. If you rev your car at idle it will smell like fuel, all cars do. Do a compression and leakdown test to see if your headgasket is bad.

ive done a leak down test and it holds compression. i do have a coolant leak but it is on a turbo line and shouldnt affect the exhaust. as far as the smell i know who exhaust smells and this doesnt smell like burnt gas it smells like raw gas?????

ive been having the same issue try checking your timing for now and tell me what u see maybe we can work out our problem together ( CAS )

i was leaning toward fuel pressure regulator but i will check the timing and let you know

Yep check your fuel pressure, also, pull your spark plugs out and check the condition of them.

spark plugs are less than two weeks old and i checked the timing and it was spot on,this may sound stupid but how exactly would i check my fpr???

You will need a fuel pressure gauge. I would suggest pulling the plugs out again, if one of your injectors is stuck open that plug will be blackas night.
