As of right now my Vortech SVT is very rough to drive, the ONLY way to get going from a stop is to rev it past 2500 and ride the clutch until 5mph. Getting to 2500 requires multiple "blips" of the throttle, as if you were to rev over and over.

Cruising around at normal speed (50mph) the AF ratio is fine. However, I will let off the gas and coast and it will go RICH! WTF? It will stay at 10:2 or so for about 10 seconds. Also sometimes it is idling at 12:1

During normal (light) acceleration in first and second gear the car pegs the wideband lean (leaner than 17:1) and in turn causes a lean misfire.

The car is hell to drive right now, and I'm about to go pick up my friend's S10 to drive everyday while he is in basic training for the Marines.

In review
*Car barely accelerates, must stay above 2000 to go....everything else bogs, even if WOT
*Car pegs wideband rich when coasting
*sometimes idles rich (12:1)
*Pegs wideband lean upon acceleration, causing misfire

What is it????????!!!!!

I fixed my vacuum leak yesterday, but it started on Sunday, but hadn't done it again until last night.

TPS Sensor?
