#199 of 1238 Jeep keeps on stalling
Nov 19, 2007 (4:12 pm)
Hi. I have a 1994 Jeep Grand Cherokee 4 liter. When I was driving it, it shut off on the highway but I was able to pull to the side. I was able to start it again but the Jeep kept on losing power...rpm's were erratic and I had to shift it into 1st gear to keep it going. I had it towed to my home and replaced the fuel filter, spark plugs, distributor cap, rotor, and wires. After all of this, the Jeep only starts when I hold down the gas. Also, when I took the jeep for a drive around the block, the rpm's would read zero if I pressed the gas and when I took my foot off the gas pedal, the rpm's would climb back but never stabilize. The jeep shudders when it is on and usually stalls. There is no check engine light and the battery and starter are new. Any ideas on what might be causing the problem. Thanks in advance.

I too am having the same exact problem with my 1998 Jeep Grand Cherokee Laredo, 4x2, 6 cylinder. Using a test light, I disconnected the positive battery cable and put a test light on the positive terminal of the battery and the other side of the test light I clipped to the unhooked positive battery cable and it lights up showing there is a short somewhere. I pulled the 50 amp Mux/T tow fuse and got the same results ( from the fuse box in the engine compartment ). I also found that if you pull fuse #7 (cluster fuse ) from the fuse box in the passenger area under the glove box and to the right ( passenger kick panel ) the current draw goes to zero, but your instrument cluster wont work either. I took everything out of the dash hoping that when the item causing the short was pulled the current draw would go away. I pulled the insturment cluster, the headlight switch box, the O/D and defroster switch box, the radio, the cigarette lighter connector and the accessory power connector and still the current draw is there. I havent found the answer yet, if anyone is out there that knows how to fix this, could you share what the fix it? I also changed to Alternator which didn't fix the problem. I also unplugged all 3 computer connectors ( computer is located on the passenger side firewall in the engine area ) still the current draw was there, so the computer isn't causing it.
#202 of 1238 cold start stalling problem
Nov 26, 2007 (7:20 pm)
My 1999 jeep Cherokee is stalling when being started cold. It needs pedal application for about 20-30 seconds to keep going. I cleaned the throttle body and checked the mat sensor and coolant temp. sensor, they were fine.the Idle air speed sensor is not in my service manual but when i unplugged it, the vehicle starts fine. I changed that sensor, and things worked great for a week, and now the problem is back. could this sensor have gone again, or is there something else i should be checking. the old sensor reads 52 ohms and the new one reads 54. Any help would be greatly appreciated. Is the idle air control and idle control valve the same thing as the idle air speed sendor??, I believe there is a map sensor in my throttle body but i don't know what the third sensor is. again my hayes service manual is not showing or describing it. could anyone tell me what the third sensor is.

Saw the same thing happen after I changed the idle air control sensor. Worked for about 3 days and started stalling again. I found that by cleaning the tunnel that the IAC is mounted in with throttle body cleaner, the problem would go away. Cleaned out this very greasy dirt that must be coming from the throttle body. What I didn't understand was how oil was getting into the intake manifold and then the throttle body. After my mechanic checked everything out, he is of the opinion that I have a leak in the intake manifold. He also noted that I had a weak battery and recommended that I change it. Incredibly, when a new battery was installed, the stalling problem went away! As I recall, others in the forum have had similar success with the Jeep stalling problem when they replace the battery.
Even though my Jeep is running better now (no stalling), I am still experiencing the bouncing tach syndrome Backing off on the gas suddenly will cause the engine rpm to drop dramatically then climb back up to a steady rpm. I am pretty sure this is due to a vacuum leak in the intake manifold. Hopefully, when we replace the intake manifold gaskets (big job) the bouncing tack problem and the oily IAC will problems will both be solved.

With all the people having trouble---don't you think its time to all join together and start a petition for a recall? On this site alone dozens having problems. We have all placed major money into repairs still not fixing problems. Anyone know how? Would be happy to sign it. Thank you.

I have a 1990 Jeep Comanche which was suffering from the same problem. Idled fine, ran on the highway but almost stalled every time off the line. After some farting around I found a damaged/melted EGR valve under the air intake just beside the exhaust manifold. It had fallen off earlier and melted against the manifold as it dangled. Luckily I have a parts Jeep in my lane way and just replaced the EGR. This fixed it right up. Because the EGR was malfunctioning I assume it was sending way too much exhaust gas back into the combustion chamber and destroying the reaction.
Hope this helps...

Bought a 2000 Grand Cherokee Laredo 3 weeks ago and have had problems with engine cutting out this week. Had to call AAA last night to rescue me. Engine sounds odd and then just dies. Refuses to restart for more than 2 seconds. Check gages light on. Told me I was out of gas, but tank is full. AAA managed to start car in Neutral but not Park. Have just left message with dealership I bought it from, but after reading all these messages I don't hold much hope. Will post again if I get this resolved.
