Well I went to emissions and luckily it passed after they gave my car a second try...but ya they said it was running rich...and I was wondering if there is anyway to adjust that without messing with the computer? I have the 350 TBI....engine runs fine....I just want to tone it down so maybe I can get a bit better gas mileage...thanx, Sean

 

either o2 or.. tbi... does it have any sort of idle air control valve?

 

ya I think it does....and the 02 sensor is new from when I rebuilt it so thats fine cause I got all my senesors checked
