don't rule your plugs out, then can foul easily.. my friend was replacing his plugs every time he filled up for gas...he was running really rich as well.. just check them, no sense in ruling them out if its been 6 days.
Also when I checked my plugs when I took them out they were two different colors. Two were white and two were brown. They looked pretty bad. I think you might be right pete. https://www.nopistons.com/forums/pub..._DIR#>/sad.png I also thought for a while I was running rich. |
white = lean.. probably your trailings right?
black = rich.. probably your leadings right? only bad condition would be if they were white on 1 rotor, and black on the other.. then you have a fuel problem. the PFC cannot compensate for a disconnected map sensor, the car would not boost and make it near impossible to drive.. you would also pour black smoke at idle because the MAP sensor would read 1bar... IE atmosphere instead of vacuum. |

well its pretty normal. but i would replace them or clean them off, also check to make sure all your plug wires are connected properly and your grounds are good.

which 2 were normal and which 2 were not?

They were just like pete said
Trailing-white leading-black When I first put the new plugs in the car was strong. Now it is so-so. This summer I plan on getting the PowerFC and an ignition pack to hopefully help out. |

mike As the white is normal on trailings, you kinda want them brown with some tips of white. Just go easy on her, and change the plugs.. lemme know what happens. |
