We have changed the fuel pump, fuel pressure reg, fuel filter, distributer it ran great for 1 day, now it sputters and shakes and dies after you start it, Please help!
Does it smell really rich at the exhaust when it sputters or not?
Check bad contact at throttle body sensor, air flow sensor, temperature sensors (plural), be sure the intake boot/bellows are not leaking (maybe the motor mount is broken, allowing too much engine movement>)
More than one issue, maybe? Also consider other experts' solutions.
First, it sounds like the EGR valve is sticking open. The exhaust valve is
supposed to be closed when idling, otherwise open. It recirculates exhaust back into the manifold; can't idle car very well when the valve is open, but should not cause backfire.
U is generally an ignition timing issue: the ECM (electronic control module) is responsible for that. Check it / replace it.
Worst case: small break in one of the head gaskets (not likely, but symptom is the same).
Vacuum leak, too???
Hope this gets you pointed in the right direction!

The problem with it was that the ignition module and the distributor. That year uses a speed density system which calculates the volume of air moving through the intake. The EMC establishes the speed factor through a signal through the ignition module there for if it's not sensing that it's moving it will shut the injectors off. I hope that this helps other people out also. The whole distributor is 115 at Shucks / O`reilly
