Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

UPDATE > High Idle - problem solved - IAC Valve ( Intake Air Control Valve )

Re: UPDATE > -- 3900 RPM in Park & Neutral, 1800 RPM in Drive -- what gives?

UPDATE >

RPMs drop when putting finger over IAC port inside throttle body, a strong suction is felt on finger.
Is the problem the IAC Valve?

Potentially, but the car should also try to stall with the IAC blocked off.

It does try to stall when plugging port almost entirely.
With about 80% of the port blocked off, it idles at around 800 RPM

I hope, but no SES light for bad IAC valve ?

Replaced the IAC valve with a new one and problem solved!
No more high idle.
Thanks guys. :th_thumbsup-wink:
