[color=blue:eed1b0287b][/color:eed1b0287b]1995 Pontiac Grand Am 4 cylinder automatic 2.3 112,000 miles 2

HELP!!!! Please!!!! Anyone!!!!! If I sound desperate,
I am. Heres the scoop.

Car has always been a good running little car. All of sudden it just died. I let it cool down for a minute, fired up.

It progressively got worse. Stalling more frequently, taking longer for it to cool down and start back up.

There is no pattern to this problem. The car will drive a few miles, then hiccup, sputter dash lights come one-engine stalls. Wont start back up until it can cool down a bit- OR if my wife gets behind it and gives it a 10 yard push, BOOM fires up and will run fine. When trying to restart it hot, the dash lights flicker real real fast (not a chance of starting)

I have put in a new alternator-battery-fuel filter-PCM-
spark plugs-boots-coils-coil housing-ignition control module-crank position sensor. No codes when scanned. I hooked the cooling fan to run when run when ignition is on (seemed to be running hot)
drove it for 145 miles!!!!!!!!!!! Ran like a dream. Thought it was fixed.
Then boom. Back to sputtering and dieing. Can start it up sounds like its running fine in driveway, put in reverse, stall. Other times,goes right along for many miles........PLEASE any suggestions would be so very much appreciated. THANK YOU!

If you car has ever overheated and is loosing coolant it may be a head gasket. You need to pull the plugs when it is running bad,. I know it isn't easy as you have to remove the plug plate and see if there is any water in the cylinders by turning it over without plugs. If so it will squirt out. Bad thing to do to hot wire the fan. Let me know

Suggested Repair

If the engine has overheated or is losing coolant, suspect a head gasket. When it is running poorly, remove the spark plugs and crank the engine to check whether coolant squirts from the cylinders. Do not leave the cooling fan hot-wired.

Conversation Summary

A 1995 Pontiac Grand Am with a 2.3L engine stalls unpredictably, often when hot, and may restart after cooling or a short push. Many ignition, charging, and control parts were replaced and no codes were found; wiring the cooling fan on only temporarily seemed to help. The expert suggested checking for coolant loss and a possible head gasket by removing the plugs and looking for water in the cylinders, and advised against hot-wiring the fan.
