Hi tjcruz,

The idling system is malfunctioning.

Check for vacumn leakages, PCV, vacumn hoses etc.

Check the IAC and its coolant hoses for clogging. Low coolant level would also cause the problem.

I already checked the vacum hoses it seems good it has some vacum, so the question is how can I check the iac valve?

Hi tjcruz,

There should be more than 1 vacumn hose.

Remove the air intake hose, do not disconnect IAT or any other sensors.

Start engine, at lower part of throttle body you would the IAC, disconnect it. Does the engine rpm goes up and hunts? Plug the socket back, does the rpm drop to 700?
If yes to the above, the IAC is ok.
