when the engine starts and is warming up the idle is supposed to be at around 1500 rpm but when the engine warms up the idle should drop to between 700 and 1000 rpm. if it doesnt drop then see a mechanic because it is a very complicated fix
below the air intake on the throttle body
the idc or idle air controller is located on the left of the engine under the throttle body
Im not a mechanic but I had Idle Problems with my 94 Dodge Stealth for a while, i did a full tune up including Distributor cap and rotor button, and put some fuel injector cleaner in with a full tank of gas and it runs much better. Of course that's if checking the actual idle doesn't work, which i believe is easily adjustable, and located somewhere under the distributor assembly.
check and or clean air idle speed motor
see previous answers, but if it idles high it might be the Mass Airflow Sensor. if your car idles too high for too long and you keep driving it, you could burn out the transmission module (very expensive )
Did you check the throttle linkage or cable?
Could be the carburetor/idle speed out of adjustment, possibly a vacuum leak
A bad idle control module will make it race up to about 3000 r.p.m. when in park.
To adjust the idle on Mazda 929 from 1992-1995.......on the top side off throttle body there is a idle air screw,turn screw cloclwise to reduce RPM. Question...is idle always high when hot or cold?
First you must check the ISC motor ( idle speed control) operation. Its located by the throttle body. It controls idle and high idle speeds. Good luck
The idle is not adjustable on a hemi. The computer controlls it by actuating the throttle valve. If your idle is too high or low you need to have sytem checked for codes.
Idle speed on a Dodge Neon is not adjustable. Idle is computer controlled with an airflow control motor on the throttle body.
