Hi guys. I'm desperate. I've just changed IACV valve put everything together start car and it keeps rev up to 2500-3000 rpm had no problem when I had removed my old one (to clean). Checked all connections, rermoved battery before install. please respond, I apreciate any input.

 

you just put new one or just cleaned and installed it back? did you mess with the idle wire i dont know what that wire called but its the one that you can adjust your rpm needle. if you installed the brand new one then i suggest that you remove it and put that old one back and see if the problem persist.

 

This is the second one this week.....What's common here?? What EXACTLY did you do? You just removed the IACV from the TB assembly and cleaned it? Or did you remove the whole TB assemby from the intake plenum with the IACV and TPS still attached and then remove the IACV? Did you remove both the TPS and IACV and clean the TB? Did you disturb the throttle idle stop screw?
