Just installed an H-pipe on my friends 2000 GT, started it up and it smokes alot and will stall out if you let off the gas. The car runs horrible, seems to run very rich. It is a Hedman off-road H-pipe, no cats. Made sure there were no leaks and tightened down all 4 O2 censors, what is wrong with the car?

frist thing is the car what is it? GT or a V6?

If it running bad and there no leaks then you o2 censors will need some MIL Elim. and if you have then it just may take some time to adjust...
