Does anyone have a good simple procedure for testing the IACV on a gems 4.0? Thank you.

If you have an ELM 327 and torque app, you can check STFT.. I suspect a vacuum leak 9/10 on idle speed issues, then dirty pendle on the IAC I scrub off and send it on that 1/10 times

I've always had a funky idle in my truck and I stopped chasing it. Two days ago I decided to put a new seal in place for the idle air control valve. When I removed it I noticed it wasn't right. I decided to attempt cleaning it up and all that did was make my drive home hell haha. High idle, low idle, stalling, you name it. So I installed my spare at home. Now I just wanted to confirm the wiring was good to go.
