stalls at idle (mopar)
 

my 1991 4.0 jeep (porsche towing vehicle) is stalling at idle and occassionally loses power during cruise speed. no codes in memory and i have replaced the crank position sensor , speed sensor (had code before) and has a new pump. what controls pump speed? throttle position sensor or the speed sensor or what? i heard that pump dying out at idle and gave it gas and pump speed (by sound) came back up as did idle speed. help please!

the problem here is that you are driving a newer Chrysler product. ;)

NOW, if they still made Chryslers like my buddys old Dart with the slant six, you wouldnt have any problems.

thanks for the link. looks like the o2 sensor ( 10k shy of the scheduled mark) was the culprit. no codes just the symptoms of a lean sporadic lean mixture.
