Running too rich.

[SUTHRNSTANG97GT]

I need some help, since I've swaped out my H-pipe my computer is not getting the right air/fuel ratio from the O2"s and its been smoking when I take off from a light , Its just a cloud of smoke and then its fine, it just does it after sitting at idle for a min. or 2 and it smells real rich. I've tried unplugging the postive batt. terminal to reset the computer and it works for a while (about a day) and then it starts again. Am i doin something wrong? I even put mil eliminaters on the rear sensors. Well thanks for any advice. ???

is this a off road h?

Yep, It's a mac O/R H-pipe. It all started when I put on a Pro chamber and then I just swapped it for a H-pipe.

hmmm, to be honest when I had off road pipes on ALL MY MUSTANGS, they always did the small amount of smoking too.........and put off the rich smell. However you said you can do the battery trip and it stops for a day and then starts again ???.........Hmmmm

what color smoke bro?

Mine does the same thing but with a cloud of blue, indicating the valve guide seals are beyond shot.


If yours is black it's the fuel.
