Engine light is on idle is high and low took it to a mechanic replaced idle control motor worked for a day or 2 and started to do the same thing again and they reset the code on the computer


If the engine is surging fast and then slow every few seconds it is most likely the air mass sensor MAF. It is sited on a collar on the air ducting just after the air filter box. Start the engine and leave it it to idle. To confirm the diagnosis there is a simple and free way to check.Start the engine and then disconnect the plug to the MAF. If the engine now begins to idle evenly (it might be faster or slower than usual but no longer surging) this indicates that it is the MAF at fault.

Idle speed to fast it variies up and down double


very likely your idle position sensor is bad. i would start there . are you showing any check engine lights on the dash? if so check which codes are showing up first as it could be other things as well like a dirty or bad MAP sensor or filiment, crank position sensor etc. ggod luck. the idle position sensor is fairly cheap and easy to replace if you have some basic tools.

Fast idle


Sounds like your throttle position sensor is bad.
Take it to Auto Zone and ask them to pull any computer codees that may be latched. Not sll codes trigger the check engine light

1.Verify that the cooling system is full of coolant and there is no air in it. 2. Remove the air boot from the throttle body and cover the throttle body with something that will stop the airflow . the Fast Idle Valve is the problem.

PVC valve is not metering air correctly, it will appear ok shaking it but looses it ability to maintain proper position causing a medium to gross vacuum leak.
