Vehicle stalls after driving fifteen to twenty minutes?

No I havent checked it, wouldnt a code come up for that, I get no codes at all.

I can't find the throttle position sensor where is it on my car and what does it look like.

The car shuts off and use a lot of gas

Hey merlin, I did unplug the Torque Converter Clutch, is there anything else I need to disable as well as just that, I heard something about a ground wire not sure. Let me know.

Just wanted to give you my problem fix. I have a 1988 ciera that was doing the same thing. Almost caused an accident doing this. I had it to several dealers and mechanics and had everything replaced like tps, iac, cat. Conv, fuel filter, the computer and software chip, plugs and plug wires, coil pack and torque convert clutch solenoid. What a grocery list huh? I asked about the egr valve and was told that it WAS NOT popping any codes. This was from at least 3 mechanics. FINALLY I found an sort of retired GM trouble shooter who is in business for himself now. First thing he found was that the dealer who istalled the computer and software chip in put the WRONG chip in it. After fixing this he drove it around and it stalled on him. It took a few days for this to happen. His computer saw a code for a problem I dont remember what but there was a tsb(technical service bulletin) that a hidden problem for that code was the egr valve. He replaced the erg and it has been STALL FREE since he installed it. This is going on 2 yrs+ now. Needless to say. He is my mechanic fulltime now and he is very reasonable. Hope this helps.

What do you mean exactly when you say backprobe, I know where it is now just need to know how to backprobe and how exactly to open throttle.

Hey merlin, I just tried disabling the TPS from the engine, the vibration in the engine went away and I drove it around the block, no more stalling issues. Is it okay to drive the car around without the TPS and the TCC plugged in, I don't have the money for a new TPS right now just wondering.

Yeah merlin, the car is runnning like a champ without the TPS plugged in, in fact it sounds better than it ever has. Let me know if its okay to drive it this way.

The car stalls after so long, one time after I drove over a curb with the RR tire it stalled just like you turned off the key. It usually takes twelve to fifteen minutes for the car to restart.

Hey merlin, you're not going to believe this after all that troubleshooting, I just got into the car to go to the store and now the engine won't turn over, just clicks and clicks. I dont know if I shorted something out or what. Let me know, my car is a mess.

Yeah man, the car died again. I was in the middle of the road this time, I put the car in nuetral after I couldn't start it, and it started, drove about halfway down the street and the engine just cut out completely. A few times again from just turning it around and trying to get it back home.

Yeah it helped when I was stranded in the middle of the road. I got it back to the house at least, it was working fine the other day now the engine just will go for awhile and cut out.
