Cleaning IAC

Can I use this carb cleaner to clean my IAC? I had some left over and wanted to know so I don't go buy more cleaning stuff when I could se this. My idle is jumpy some times and won't idle with my AC on. I had the CEL on with a P1507 code but the light went off. Still wont idle. Wanna try to clean the IAC to see if it helps. Thanks!

Ok thanks, it's also safe to spray inside it right?

Also what is the box on the IAC hose? I blew through it and it seems like it's restrictive

Carb cleaner does it for me. Basically anything that can clean out any debri or buildup.

Well my car idles now, before it didn't, but not it just drops really low (like 200-200 rpm) then stabilises. Could it be a vacuum leak? Or is this a sign the iac is bad

Hey i had the exact problem with the dropping idle. I got my IAC replaced and still had the problem. If you look under your hood it happens because the Air Conditioning unit will snap on/off causing the idle to dip. Im not sure how i fixed mine but i just disconnected my battery for the PCM to re-learn the idle. I put the air on full blast and drove around a bit, this helped a little bit. After some more driving i think it fixed itself(lucky me). Just Reset your Car and try driving it around so it can learn.

I have also heard that your A/C Pressure switch can cause the compressor to act sporadically. Best of luck to you man, its an annoying problem.

I will try that as soon as I'm home! I was thinking it might be something with the compressor, like maybe it's starting to seize up or something. Ill let you know when I do it
