I just got a '92 and it ran fine for a few days and now it shutters and dies whenever i accelerate or even when i am slowing down, or at a stop. I have tried almost everything i can think of but nothing seems to work. I think it is a wiring problem because it seems to die as soon as i hit a bump or pothole.

 

could be a clogged fuel filter, or the fuel pump is dieing, and also the map sensor could be going bad, my camaro did the same thing when i bought it it turned out the the number 6 and 8 cylinder wires were crossed and the map sensor was bad, as soon as I corrected the wires and changed the sensor it ran fine.
