I have read through a lot of idle topics the last few days but couldn't find anything that matched my issues.

I would turn my car on and it would idle at 2k rpms until it warmed up. If I would push the gas pedal the needle would rise and take some time to come back down to idle at 750 rpms after it was warmed up. I'm not sure what caused this. I ended up cleaning the IAVC and now my car idles at 100-200 rpms

I tightened the bolts on the IAVC real tight so I don't think it's a leak. Anyone have any ideas on what would cause this really low idle and what would cause the rpms to take time to drop down after i put my foot on the gas? And before I cleaned the IAVC when I would drive and take my foot off the gas the needle would drop down really low and then go back up to the normal idle. Any help is very much appreciated!

 

bump for any help, thanks.

 

how long are you letting it warm up?

 

sounds like a bad iac control

Is there a way to test it?

5-10 minutes usually.

 

throttle cable adjustment to start?
