Hello, My name is Ryan. I have a question about a Jeep Liberty. 3.7L 6 cyc. Auto with AC.
The Jeep was driving when the RPM started going extremely high. The Jeep has a new battery (6 months ago), Automatic trans. The problem happens all the time now. It happens with the AC or without. Previously there was a problem with the Jeep stalling. The RPM would go very low then stall. I had the stalling problem addressed: a mechanic cleaned the sensor for idling speed and that helped the low RPM for awhile. It worked recently and stoped the stalling but it did stall again recently (only a few times in the last few months not like before the cleaning) I wanted them to change the sensor but they did not have one (I brought the car to Mexico for my vacation place). Sometimes this prohibited me from using the AC. Now the problem is the opposite-the RPM goes really high. It started on the highway but now does it in traffic as well. The car is in Mexico. It is VERY humid here. Sea level altitude. The check engine light has always been on on this vehicle for the last few years along with other lights on the dash (ABS light, brake light, engine light). The jeep recently had an AC swtich be replaced. Seems like the truck always has electrical problems. The transmission seems to not be shifting correctly during the problem. Gas here is very dirty, I had run the tank to very low (supposed to fill on 1/4 tank to avoid the dirt from the bottom of the tank is suggested here). I am not sure if that could be part cause. The truck is pretty much undrivable right now. The mechanics here are not very good. They are especially poor at diagnosis. I would appreciate any help you can shed on this matter! Thank you.
have the same problem?
