Stopping the irritating "Perform Maintenance" signal
Other than taking it into a shop, can we stop the overhead signal of "Perform Maintenance" which occurs every significant mileage point? I take very very good care of my 02 Jeep GC and don't need this reminders at 60, 72, etc miles. Thank you!

your evaporator heater core drain hole stopped up not allowing drain on outside.look under vechicle below firewall look for drain hole try up stopping it using shop vac with a small tube or rubber hose tape to shop vac hose try vacuum out debris stopping up drain hole.
- Remove the negative battery terminal.
- Remove the Mass Air Flow (MAF) sensor, hold press a contact cleaner spray at the distance of about 6 inches on to the two tiny filaments located deep in the MAF sensor barrel, hold it in inverted position and let it dry.
- Fit the sensor and reconnect the connector.
- Start the engine and perform idle speed relearn procedure. It should now perform well. If not, then check the fuel pump pressure.
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
This is a oil change reminder. Nothing fancy about, when you get your oil change go into the menu and click reset counter and it will go off. If there was something wrong with your car the check engine light would come on.
Sounds like your timing belt is one tooth off on the cam, this I have seen before especially if it is a twin overhead cam. One tooth off will make it idle really low when stopping at the light especially if the engine is warm.
well it seems to be an transmission problem. when you have it under load(in gear) there seems to be resistance that stalls the motor. the engine speed sensor sends a signal to the ecm(engine control module) this in turn sends a signal to the trans control module. from there the signal goes to a solenoid inside the trans the shifts the gears. somewhere in that circuit is the problem. you need to take it to a shop and have a scan done, this will isolate the problem. please rate this ..thanks
