Not sure what is Causing it to idle high. Any suggestions?
Thanks

I cleaned it last week. Maybe it needs to be replaced?

Likely either a dirty IAC or orifice it fits into, which can be cleaned, or a vacuum leak.

I just realized when I first start it it’s at 800 but after driving around awhile is when the rpms won’t drop

Pull the MAP sensor and check the rubber elbow. You may be able to get the elbow off without removing the sensor but it's pretty small.

So I re-cleaned the IAC and orifice. Found a vacuum line that was loose but still attached and put a zip tie on it. Now seems to ideal around 800 rpm from my quick trip around the block. Hopefully what ever I did fixed it. Thanks for the info.

800 is still a tad high, no? Unless you have AC on.

Summer time in Texas. My ac is always on full blast lol
What should idle rpms be at when the ac Is off?
