Question about 1990 Jeep Cherokee Limited
My 90 Cherokee cuts out often when barely applying the throttle. It is a manual, 4.0 with out A/C.
Fuel pressure test indacates that the fuel pressure goes from 31 to 35 when it cuts out. Runs great idleing, and running down the road, but when you barely apply throttle it tries to die. Good mat sensor, good fuel, new fuel filter, added "HEAT" incase of water in tank, and added STP injector cleaner. does not throw a code. Any questions ask so I may help diagnose issue. Thanks, David
I had this same problem, and honestly no one could ever tell mme what the real problem was. So I just started replacing everything when I got paid. I even changed it over to a msd distributor and ignition system. I replaced alot of sensors but to be honest I don't know what ended up fixing it. I had to replace a couple of fuel injectors that the jeep dealer swears up and down didn't have anything to do with the problem. The dealer nor any mechanic I went to could tell me anything. It was just replace everything till it went away.

Check you distributor grab it and see if its loose. if it is check to make sure its tightened down. and if it is tight and it moves around you need a new one. another thing to check is if you have a cat. it may be plugged and the excaust is not flowing. try unbolting it and see what happens
