I guess I trust the guages as far as I can throw them, got them at Advance Auto for about 30-40$ bucks. I tightened the manifold bolts earlier today, none were real loose. I got a shitty, but not as shitty as usual idle after I cleaned the IAC and TB. I also reset the computer, and hooke dhte...

ROE Thanks for that suggestion. I changed the CAT about a year and half ago to a high flow cat, along wiht a new muffler. I will beat on the CAT to see if I hear anything chunky, but because the Jeep runs great other than this bad idle, limited RPM to 3000, and stalling stop signs, aka the bad...

I have heard 20 in of Hg, but I am still trying to confirm, mine is at 8 right now and my car runs like crap But it sounds like the canister may hvae fixed your problem? eze

ok , I did the whole vac test, by plugging each one. I think its strange that it could be a valve or cylinder problem when the thing runs great between 1000 and 3000 RPM. I can also only drive it with the MAP disconnected, otherwise with the MAP connected it stalls alot and cuts in and out at...

hey thanks for the advice, I took each vac 'takeoff' line off and plugged it with my finger, one at a time. There was no change in vac pressure as I removed and plugged each one. So i am wondering if I still need to plug them all at once and take a reading? I though maybe the manifold was...

ok so I did another vac test, its now 8 in hg, so I think i definately got a vac prob. Now I keep the gage on, and pull and plug various vac tubes off the intake manifold with no change in vac pressure, does this mean intake gasket or something? Any other ideas on where to look? I thought I read...

DAMMIT Problem is back. I noticed the wires were looking frayed at the MAP sensor connector, so I resoldered those last night. After the resolder job, the original problem I posted is back,. the idle is randomly rough, the 3100 RPM shutdown cycle is also random as to when it occurs, the motor...

Bob I have a 96 xj with over 160k. I have a problem, not exactly like yours, but a frustrating one none the less. My jeep would not rev past 3100 rpm. I replaced the MAP, CPS, TPS, cleaned TB, went through wiring, paid a mechanic 400$ to find a burnt out connector on the PCM, but the problem is...

The bad 'spot' was the where the wire terminated at the PCM connector pin itself. This wire was one of the 3 from the MAP that runs back to the PCM. I was on the right track, my mistake was not checking continuity from connector to connector, as I only probed the wire right BEFORE it goes into...

379$ dollars later I had to laugh when the mechanic told me "this problem had got me by the balls" Well, the problem was a bad wire (green w/red stripe) in the actual connector to the PCM. You would only be able to tell this if you checked continuity between the sensor lead and the INSIDE of...

I paid 104 at the dealer a few weeks ago... I also understand ther is a high altitude CPS dependent on where you live (above 4500 ft)

one other intersting note, if I disconnect the MAP and reset the computer (via battery disconnect) i immediately again get the CODE 14 MAP I also noticed a clicking sound near the main enginer compartment fuse panel with KEY ON ONLY when I backprobe Nos. 1 and 2, or jiggle random wires..but I...

I was thinking that, I did a fuel pressure test a few months ago, and it was fine at both idle and reving, but I guess it would be tough to test under load. Any ideas on how I can test that short of having someone ride in the engine compartment while watchin the gage..hehe I dont hear the...

thanks guys, I checked the elbow, its good by using my 'blow test' with fingers I also double checked the resistence for the three leads of the MAP, as well as swapping in the old MAP, all no change. still on the hunt, I suspect maybe a wire is open from another sensor that shares this circuit...

yes, I got the CPS from the dealer. The harness looks ok, and i didnt see the infamous burnt wires. I was also thinking maybe PCM is going bad? or i have an open in a wire? I am so stumped and frustrated. I have it scheduled in a shop for Friday, but I really am trying to avoid that visit. I...
