Ok here it is. I blew a head gasket about 6 weeks ago and since then i have been having some problems. I have replaced the O2 sensor, the ESC module, cap, rotor, wires, plugs, egr valve, egr solenoid, knock sensor, timing chain, water pump, changed the synthetic oil, and had the exaust leaks all taken care of. up until yesturday the car was running pretty good, but today the car started and then died. to keep it running i have to press the accelerator while driving to keep the car from dying. somethimes the car's idle will flutter a few hundred rpms while in park or while stoped at a light. i have checked and replaced the vacume lines and have no idea what the problem is. if anyone has any free knowledge on this i would appreciate it greatly

Thanks:hail:

 

I'm going to make a safe assumption that you have a TPI motor, since it's a 350.
Since you had the top end apart(for the head gasket job) have you re-torqued the intake, including all the bolts to the runners??? This motor's touchy about vacuum leaks.

Also, look into the Coolant Temp Sensor (check codes?). Mine had the same symptoms untill I changed it.

 

Perform a search for "idle" and RPM". There should be lots of similar topics. The first thing to verify is the TPS, and you need to have a clean throttle body and IAC.
