If you have a multi port fuel injected 6 cyl, it's probably the idle air control. I have
replaced mine a couple of times over the years. 2 screws and it plugs into the
throttle body next to the throttle position sensor. Costs around $60.
Jeep Comanche was created in 1985.
The price of a Jeep Comanche ranges greatly depending on the car's model year. A 1989 Jeep Comanche costs roughly $3000, while a 1988 Jeep Comanche can cost anywhere from $2000 to $4000.
Idle is computer controlled and can NOT be adjusted.
No, Cherokee is a wagon, and the Comanche is a pickup, but on the years they were made the parts will be the same.
Idle is not adjustable. You have a electrical or vacuum issue that needs diagnosed.
You shouldn't have to, check for vacuum intake leaks
no
go to www.google.com click on images and type in 1989 jeep comanche multiple images will appear
No.No.
Yes
Could be a vacuum leak
theres a cable connected to a little turny thing near the front and center of the engine at the top. thats the throttle, its what your gas pedal controls. on the turny part there is a screw that the assembly is resting against, the idle adjustment screw. run the engine and adjust the screw til you get the result you like. I have done this on my 89 jeep comanche to make it easier to drive cause when I was new to standard. dont adjust it to high or low though. I would stay within the 700 to 1100 rpm gauge or it can be bad for your engine or environment. hope that helped
