I just installed a new IAC Valve but the idling is at 2200 rpm. However, when I put the old one back - it's around 600 - 700 rpm.
I changed the IAC because I thought it may be time for it. But now I'm thinking I should leave the old one and call it a day
What do you guys think?
Thanks in advance.. SMA
My car has an automatic transmission.
