changed the throttle position sensor. that wasnt it either. :? it seems a little bit more responsive, but it still dies and has that damn code. i'm done guessing, im probly going to save up money and take it to a stealership to have them diagnose it. the only other thing i can think of is the MAF. or could there be a problem with my computer? it still hesitates when i push the pedal down(around 1k rpms).
Just learning these cars myself, but have you checked the EGR valve/piping? Possibly could be clogged malfunctioning.... i think the EGR would throw it'* own code..but just a thought

hmmm....didnt think of that one. there is def. a smell when the car dies. i was just thinking it was because the A/F was off. im assuming its lean, it doesnt smell gassy, kinda more like burning charcoal.

alright, talked to a buddy at a dealership, he suggested swaping MAFs with somebody to see if it works. also, another friend suggested it might be my crank and/or cam position sensor. both of them went out on his '95 bonnie. would there be a way to check that?
do you show a misfire code?
if so, crank or cam sensor possible...but im not sure if either one wouldn't throw it'* own code.
only time i have had a crankshaft sensor issue was on a 2000 suburban i swapped motors in. after swapping, i kept getting misfire code...... finally after 800 in other "fixes" by dealer, they relearned the crankshaft sensor to the comptuer...and all was good. but, that was a different scenario.
last friend i mentioned it to on his S10 of having crankshaft sensor checked... i beleive dealer said there is no way to check if it is right...they just relearn it..otherwise if it was bad...would throw a code.
camshaft....not sure there.
i would swap mafs with somene that has a SSEI same year as yours and see if that helps... maybe forum member has one they could loan to you to try...if they have a spare?
