I have a 95 Grand Cherokee Limited 5.2L V8. I just bought it as a project car but it has some issues and I'm not sure where to start. It starts fine and runs great UNTIL it reaches operating temp. Once it hits that temp it starts idling irraticly (mostly low idle aka. under 1k rpm's) and will eventually stall. It will start right back up but than will stall out again. It also didnt pass NOx emission test so I know I have a Fuel/ Air mixture problem. Any advice on where to start would be greatly appretiated!

I am new to this forum... I have a 2001 Jeep Grand Cherokee Limited with a 4.7L V8 engine. Like many JGC owners, I had had many problems along the way. Last week the car began acting out during start-up and would die immediately after a start (after trying several times) and would die in idle if the gas pedal was not pushed down to supply extra gas. The lights would dim, the car would make a big hesitation as if dying out with a faint crank. After turning the key several times to start the car up, it would start and would die immediately in idle if extra gas is not supplied in high rpm idle by pushing the gas pedal... The lights in the car would otherwise work fine, the gauges, the power seats etc would function... The voltage gauge would show 13-14 volts on the dashboard analog gauge once it went through a successful start-up by supplying extra gas for 30-60 seconds. This went on for about a week until I replaced the battery yesterday and all the problems were solved... My battery was an AC Delco battery with a 7-year warranty and had just completed 4 years of use this month. I was thinking either a malfunctioning TPS, an IAC valve or a crankshaft sensor, but wanted to take the battery question out of the way first... Reading this post last night gave me this idea... I appreciate all the help... and wanted to give a feedback...
