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!
