Hey all,
I think I have an issue with the IAC valve. I pulled codes 21 and 24, and the car won't start. It turns over, but won't start. It used to have a hard time starting, and I could tap the pedal to the floor, and in most cases it would catch and start running. Now, it just turns over, and it sounds different than before.
Also, looking into the throttle body, I see oil has come up from the valve covers and blackened the throttle body, as well as some oil coming up from what looks like the transfer case/differential (?) - it's a larger sized hose that connects to the bottom of the air intake.
So, I have followed what I could in the Haynes repair manual, and the resistance readings are 30.4 and 60.4 ohms, whereas the book says it should be between 7.3 and 13 ohms. I've gone to one junk yard already and checked the resistance on that valve, and got the same as mine (30/60 ohms).
(Already replaced the engine coolant temp sensor, but the IAC valve is at least $380.)
That's where I'm at, and heading to another junk yard.
Thanks in advance.
