I changed the IAC valve to a new one, cleared the codes, then started the engine.
Still doin the same thing, throwing code 14, IAC valve and car idles at 2000rpm and bounces.
Do you have a manual with wiring for the car? If so go over it again, trace wires. Then look for something like, I don't know, and bad seal on the intake, or coolant levels, or something. There's a whole slew of things that can cause high and irratic idling.
