suggestions, black smoke
i had my girlfriend rev up to 4.5k again and the black smoke seemed to start coming through my exhaust at 4k and up. am i running rich or is there another problem? any info will be greatly appreciated!
any codes (probably a code for the 02's)
you need to log and see what is up. look at it this way, it isn't white or blue smoke
being a little rich in the upper rpms never hurt anybody, just performance... Trending Topics
