just a quick update..... Car fires up just fine. It will sit there and idle nicely as long as you have your foot on the accelerator.( It will idle around 800 rpm). As soon as let off, the car starts to stumble, decreasing in revs until it dies.

The whole motor has just been rebuilt. has new plug wires, plugs, just about anything that you could think of that needs to be maintained.

I checked quickly for vacuum leaks last night when i fired it up. I didn't notice any large leaks. do you think a small vaccuum leak would cause such a problem?

In the meantime, i'll test out what you all have posted thus far.

Thanks.

To verify that the splugs/wires are working pull them and see that they are firing. Be sure that they arent some ungodly gap while you're at it.

A dirty throttle body Id imagine isnt the case here as that would likely just cause the throttle to stick instead of simply not working.

Id check for huge leaks the in the intake path first off. I believe theres an idle bypass in the throttle body itself which could also be the cause. Vaccuum leaks are also another possibility so check those out, however it sounds like one hell of a leak for it to do that. Just go out and spend some time checking it out and report back.

My isc went bad a few weeks after i bought my car. i just disconnected, adjusted my idle screw and went on my marry way... and idea wtf is the point in that isc anyways?

P.S. My car did exactly like yours because of those two stupid little dry rotted o-rings in the TB at the part where the butterfly valve is. I replaced them and it was fine again

Thanks a lot for the advice so far guys.

Just wanted to clear up too that when i said the motor was rebuilt, it has been swapped over to a six-bolt.

I'm running accel wires. I'll def. check tho to see if they are all firing properly.
