power. changed plugs, throttle body cleaning but same problem exists and their is no
engine check light on running engine. what is the possible problem?
Did you also clean your IAC? (Idle Air Control Valve) If so and no results, you may need to replace it. Here's a short video: https://www.youtube.com/watch?v=mfauGoGXCmo
didn't clean IAC. but if there was a problem with IAC the chec engine light should glow?
I don't think I've ever run across an IAC code. It's easy to clean. https://www.youtube.com/watch?v=C419kwrH0vE ttps://www.youtube.com/watch?v=ez5ykPAMG8k
