Aloha,
I have been trying to figure out why my car has a very low idle. The car idles at 0, obviously not 0 but it looks like 0 on the dash, when you rev it moves so it is not the dash or tach.
Items replaced to try and fix the issue:
- Air intake system - entire system replaced
- Valve cover and spark plug seals
- Vacuum leak checks but it still may be, but highly doubt this one
- Compression test - everything is perfect
Does anyone have any ideas about what it could be or what I can check at home to fix this issue. Thank you very much for any help anyone can provide.
Mahalo,
Justin
You said entire air intake system but did you replace the idle air control valve on the throttle body? Mahalo.
I replaced the house and air box assembly. The idle air control valve has not been replaced and is not pulling any codes. If that was bad would the idle not fluctuate up and down rather than be super low? I am planning on cleaning the throttle body and IAC when I receive new gaskets to replace the old ones with.
It's certainly worth a try. Mele Kalikimaka.
Yeah, it is a $400 part so I don't want to keep replacing parts if they are not the cause. Do you know of a way to test the IAC to see if it truly is causing the issue? I have already unplugged it and ran the car for a few days, starting, stopping on and on. It didnt help anything so I was assuming that rules it out?

Rock Auto has the part #AC194 for $116.97.
Sounds like you are confident it is the IAC, I found it on the site that one is the wrong one but here is the correct one for $140
