Black smoke is perfectly normal. The car was tuned to run rich for safety reasons. Unless its blue/white smoke, nothing to worry about.

Getting on a car when you're low on gas...that kinda answers itself.

i wasnt really low i had liek alittle less then a quarter of a tank left..and y wouldnt i have low acceleration??/ my friends said maybe fuel injectors that hey are putting in too much fuel and r gettin soaked

How many miles on your car? Running rich like they do on a factory tune and 50k or more miles would have me thinking front O-2 sensor having a slow response to change. Not anything you would see on a DVM but I have had my fare share of 'going bad' O-2 sensors over the years and the fat (rich) running cars having issues earlier on than the ones running clean Fuel/Air ratio's. You may check to see if there are any 'pending' codes.

i onlye have 25 055, and my a/f ratio is 14.2 im thinkin it was the fuel injectors..ne chance thats it..that the yr gettin flooded wit fuel??

I think you have something mixed up. An A/F of 14.2 is almost optimal. If a car is running rich (too much fuel) that number will be lower like say 10.2

[04Redline0124]

well its 14.2 i just got a dyno

Then you have the best (almost stock) stock A/F curve of any RL on this board I'd say.

are you sure you were in 1st instead of 3rd?

Not if he's at WOT.

That would be pretty damn scary if he's getting 14.2 at WOT.
