So, first I unplugged the harness from the ECU, and checked a few, then I plugged it back in, and checked them all again by "back-probing" the pins in the blue plastic plug....
Anyway, all ground were exactly 0 Ohms.
So, I fire up the car, and go out for a drive.....well I drive the car for 45 minutes, and VOILA, PROBLEM GONE.....I revved the car out to redline at least 15 or so times with not a single hiccup at all.
Then I took it out tonight again for over an hour and again, not a single problem.
This is SO FUCKING WEIRD......I can't imagine that it was bad contact of an ECU pin, because I have unplugged the ECU from the harness at least 10 times in the past 2 months during this troubleshooting adventure.
Furthermore, when the problem started, I hadn't touched the ECU for a reallly long time.
Lastly, I should add that during the drives, the ECU was out in the open, not inside the kickplate.....
It seems obvious that this is either a bad connection somewhere, or still possibly the ECU.....maybe the ECU didn't get as hot today because I didn't have it covered by the plastic kickplate?
I am COMPLETELY befuddled on this one.........but also kinda happy that I was able to drive my car again (well, actually being able to rev over 4K) for the first time in like 5 weeks.
I wish I could know what the issue was so that I could feel like I resolved the issue and maybe help out others in the future....but for now, problem solved, but NOT sure why.....
