Car isn't running right.
I just replaced the IAC in my car. After I replaced it, when I rev the car up, it takes 3 or 4 seconds for it to rev back down. When I drive the car, I have to wait before for the RPM's to drop before I shift!
Another problem, not related to the above, is that my tach won't drop below 4000 RPM's. When I get on it, it will move up some and then stop back at 4000.
Any Help?????
