91 cutlass supreme stalling problems

1991 cutlass supreme
148,000 miles auto
3.1 L v6

at first the car would not run for more then a few minutes without sputtering and then stalling, once stalled the check engine light would flash along with a loud clicking noise, the cooling fans would come on/off at every click, so we figured it was an electric short with the fans power so i removed the fuses to both, it will now run for a little bit longer but will still iether start bucking and then forcefullly stalling or just idle way to low and iether have to have the IAS removed it order for it to idle high enough to stay alive or keep your foot on the gas.

also the car always seems to have air in the coolant lines, ever since i replaced the water pump there has been an insane amount of air in there, to the point where i spent 20 minutes bleeding air out of it with only a little gain in the time between overheating (dont think its fan related as going over 45+ mph doesn't help much)(know its air becuase the heater will get REALLY hot and start to overheat, or get ice cold and start to overheat (like air is blocking passage)

so do you think its the ECM or the TPS?? i'm going to go have it scanned soon so hopefully that will turn something up.

when the car first starts cold, it runs like a beast

forgot to mention, after stalling it wont start back up, have to come back in a few hours and it will work fine for a litle while

My 89 cutlass had the same problem. I first had the fuel pump replaced, after that I had the TPS replaced and she runs good now...So far.
