I've read that drilling out the upper mounting hole will get my cps a hair closer to the flex plate BUT that is just close enough to improve the voltage to a much more respectable reading. My problem is, I haven't read anything that clarifies which hole. Am I drilling the mount hole on the bell housing or the one on the cps bracket. And this is my first post so I'll let y'all get the flaming out of your systems now with a second question. What in the wide wide world of sports are us early 2.5 (1987) TBI remix guys supposed to do when we need a MAT (NOT MAP) Sensor? NLA -
On the passenger side engine compartment on my 89 yj 2.5 liter there is some diagnostic plug in connectors. which one is the connector for the isa motor control? Which one is D-1 and D-2? How are each individual holes in connectors numbered ( 1-2-3-4-5-6 etc>)? -
Hello to All.... I wish to thank all the members and especially you Mr. Ludell for all the time spent on our endless problems.... I have reviewed all the posts that might pertain to my problem and do not wish to ask a question that can be easily answered by simple review... My YJ has had an.. "on again / off again" problem that may not be related to this exact problem but it just seems to have never been 100 % or maybe even 80%... The current problem started on an outing in the woods ..drove fine climbing, downhill and 4wd.. coming back the engine began to act like it was -

How may I test the idle speed actuator in my 88s 2.5L4 MJ is still ok? got the feeling there's no activity from it! maybe the wiring, or the isa is broken? Changed the isa though!! thanks from Germany!! kalle -
My son just purchased a 1990 Wrangler with a 2.5 4 cylinder. We noticed that it had oil leaks and coolant leaks that needed to be addressed. So we replaced the radiator hoses, heater hoses, heater core, thermostat, and thermostat housing. As we were bringing the Jeep up to temperature to ensure there were no leaks from the hoses we had just replaced, the engine died, as if it had ran out of fuel. The gauge read 1/2, but to be safe, we added fuel and tried to start it. No start. I checked for spark, and we had spark. I pulled the spark plugs out of the engine and cranked the engine ov -
At random times I start my 1990 jeep wrangler tbi. It starts fine but its idle will go up to 3500 and stay there until I shut it off. But I go to restart it and it starts normal -
Moses, I made a video of the Snap-on MT2500 scan tool readings maybe this will help in the RPM issue. Here is some history of the 89 Jeep Wrangler YJ 2.5L. I have what i call a hiccup when idling or driving every once in awhile. The engine is usually warm to operation temp and will hesitate or act like it dies ( rpm drop at an idle to 200 rpm or so) while idling in the drive way. Sometimes will die but will start right back up and there is days when it dose this hiccup while i am going 25 or 45 mph or what ever speed and has no rhyme or reason. Here is what I have replace or trouble sho -
Hello, first off let me begin by saying thank you to Moses for your site. It has helped me fix a lot of issues with my jeep. I have a 1988 jeep yj with the renix 2.5 tbi setup. The problem is that the jeep starts and runs but consistently spit, sputters and stalls. I can be driving down the road doing 55 mph and then it is like somebody turns the key off and back on again. it does this at idle as well. Things I have already done/replaced: new cap, rotor, plugs, wires, coil, ign. Module, ign. Switch, and the cps. I have gone through and tested the coolant temp sensor (for the ecu -
I've got a very stubborn jeep that just won't stay running. I've been fighting it for a year now. And since has improved. But I've been just uses sing and I need a way to solidly diagnose what's going on with it. It has a 2.5l 4cyl Tbi. The issues I'm having is most defiantly effected by the weather and climate and time of day. But the issue seems to mostly fluctuate with time of day. 1. So in the morning at like 5:25am I start it to warm up before I leave for work and it'll start and run just fine till it got to be about 100 degrees then it'll idle down to like 300 rpm and stall ( unless i fl

1990 jeep wrangler with the 2.5l 4cyl engine. it was rebuilt about 10 years ago its got 100,000 ish on the engine. About 4 years ago it started making this noise. Some people thought it was a diesel engine. oil pressure test confirms somethings up. The needle was some what jumpy. It only does it when the engine is warmed up. I suspect its a lifter issue or a spark knock. Any ideas?
