Keeps Dying?????

Alright, heres the scenario...I will start the Jeep up in the morning and it will run just fine on my way to work. Most of the time on my way to work I stop at Albertsons to get me a banana and orange juice. Well I will get back in the Jeep and continue the trip to work. After that time of starting the Jeep up, if I come to a stop it will just die. I have to keep my foot on the gas pedal a little bit and put it into neutral and use my left foot for the brake to keep the Jeep alive. I just (last night) replaced my MAP sensor and Throttle Position Sensor (TPS). What else could it be? I know I couldn't have put the MAP on wrong or the TPS on wrong. Is it a bad alternator maybe???? I replaced the TPS hoping to fix this problem, but apparently that was not the fix for the problem. Please help, PLEASE!!!

Check your IAC and clean the throttle body thorughly. Do a search, there are plenty of threads covering the cleaning process.

Alright, now that I figured out what IAC is....(idle air circuit) Where is that located on the engine, I'm assuming that it's near the throttle body somewhere. Can I replace it?

Also, could it be an alternator with those symptoms? or maybe my starter is bad???

Thanks, my Jeep is an 89.

It may be the EGR valve staying open. First I would see that the valve moves freely. Then I would disconnect and plug the vacuum line that goes to it. If it doesnt act up any more with the egr valve vacuum line disconnected, then you will know that your problem is in the egr valve area.

Thanks, I will check that tomorrow.

Thing being, I what does "EGR" stand for?? Sorry, way too many abbreviations for me.

EGR... Exhaust Gas Recirculation
