I just tried installing 2 new IAC valves today. Checked them all (including my faulty one) before continuing, and all of them moved with the turn of the key. Installed the first one and all hell broke loose.

car didnt respond well to the IACs at all. they are aftermarket. Car now will not respond to the biss screw and its idling at around 800 when its set for 1000.

I put my old one back in and same problem. I reset the ECU by disconnecting the negative. No results.


WTF

 

edit: I'm an idiot. DV came off the intake
