A part called an idle air control valve. It should be near the throtle linkage. But one from a parts store, change it out and see what that does.

Why does my 89 jeep comanche 4.0 have a high idle upon start and sometimes while driving. t has been only doing so upon sart but now it does it randomly while driving.


Most vehicles have a high idle until the engine gets hot. As for your random problem, might want to check for any vacuum leaks that could cause this problem.

When checking, best to do with cold engine. Start your vehicle and spray short amounts of starting fluid near vacuum hoses, if idle changes, you may have a leak. Keep away from exhaust manifold if at all possible. Also spray near intake hoses and air filter housing.

My jeep Comanche will not start unless I put gas into the carburetor then it will run fine.


Check fuel pump for operation. Check for blocked fuel filter. Check for problem of tank not venting and creating a vacuum that will not let the fuel to be pumped to the carby.. Check that the needle and seat in the carby is not jammed closed or the small filter at the inlet is not blocked

1988 jeep comanche idles high. have checked vacuum hoses. what could be causing this?


You might try adjusting the idle at the throttle body, check the mass airflow sensor, and check for leaks around the plenium.- or what some people still refer to as the intake. And, check the condition of the fuel rail and injectors.
