I have an 89 Jeep Wrangler with a 6 cylinder 2.5 liter engine, manual tranny and no AC, which occasionally will stall out when stopping at a stop sign or when down-shifting while going into a turn. Even when driving on a straight road I’ve found that I can be in 4th gear for instance and at approx. 3,000 rpms and if I push in the clutch and let off the accelerator sometimes the rpms gauge will take a nice smooth ride to about 900 rpm’s and sometimes it’ll drop like a rock, dipping down to 400 or 500 then settling back up to 900 or 1000. In the past year, we’ve put in a new engine, clutch, fuel pump, plugs, wires, cap, and alternator. I’ve had it to 3 different mechanics and had the camshaft sensor replaced, the throttle body cleaned out, the timing checked and the ACI actuator replaced all to no avail. This is supposed to be my daughter’s college car but I don’t feel safe in letter her take it with this ongoing issue which has been happening since we bought the car 5 years ago – before all these changes we made.
