Idle drop by 500 rpm?

It's ok. It's not you. I'm trying to give you a diagnostic map and you're gettin railroaded around every corner. I realize now I just caint do it from here.

Good of you to help out @RustyRatRod

Hopefully some of the guys looking in learned some of the diagnostic steps on how to go about this.

Over the internet diagnostics, no easy task.
