stalling
I have a 94 jeep cherokee sport,151,000 miles, 4.0 liter inline 6. Central Michigan. The engine stalls. Driving down the road after about 40 mins and in the driveway after about 15 mins. I've changed the fuel filter, coolant temperature sensor, gave it a tuneup, fixed a bad ground, and put a 180 thermostat( had a 195) in it. It runs great, when it runs. Starts right back up after it stalls. Any help would be greatly appreciated.

RE: stalling
First thing I would do is try cleaning the throttle body and the IAC. (Idle Air Control) The IAC commonly doesn't respond fast enough when it's dirty so it may stall out after jazzing the throttle or possibly in traffic. I would also go back to the 195 t-stat, especially for the winter. The ECM may not like the lower temps when the weather changes. Everything in the system is calibrated around 195 degrees and that part can't be changed.

Let us know if this helps. We can post more if you are not sure what to do.
