need more info but just guessing here vacuum leak causing high idle and dieseling cause by high fuel air mix why it will not shut off
Loud idle? no, not turn over ,yes
Could be you need a new fuel idle motor. Or you need new spark plugs
Either the car wont start or, it will not idle right (its going to fell like its going to turn off).
Turn a couple screws on the carberator; set up the "idle".
Usually the spark plugs or the timing.
Does it turn over? Does it turn over?
The A/C idle compensator solenoid is not functioning. This should be located next to the carb.
Start with checking the fuses.
Hi, The battery has enough power to turn the starter, but not enough to run the computer. You can test it this way. As you try to start the engine, give it a little gas to keep the engine running above idle. If it runs above idle then dies at idle it is the battery. I have had this happen twice in the 10 years with my 2000 Durango.
Check the idle sensor if you have one.
Turn the wheel and then try to start it with the key.
Check the throttle position sensor or the idle control motor
