Running rich ?
Hello,
New to this forum. I have a 440i BM3 stage2,HPFPTU and Vader solutions PCV delete. Yesterday I turned my car on and the car did not sound so great. Drove around and my exhaust sounded low. My car is straight piped. Took a look at my spark plugs and they’re black. I recently a swapped the plugs out last month cause the pcv failed on me, and there was oil all over the plugs. Is this normal? Happy New Years. |
