Welcome to the addiction.
the reason for the right rear tire usually spinning first is due to the rotational torque of the driveshaft trying to lift that wheel, causing it to have slightly less contact area and weight.
Bingo!!
There was and adapter to use the Chrysler DRB on the Renix Jeeps. I have one.
The MT2500 "brick" can scan it also with the correct adapters.
No stored codes or anything, but reading stuff in "real time" has worked for me.
Then it may be a thermal problem. Something gets warm and fails monentarily, cools off, and is then okay.
How tight are the connectors on the fuel pump ballast resistor?
No wait time? Why don't you at least take a gander at the ignition switch up under the dash on top of the steering column? Maybe it's crispy looking?
So, the temp gauge stating normal points to the ignition switch working in the On position though. Tach dropping could be bad CPS or just the fact the engine died as well as the oil pressure reading. The fuel and voltmeter gauges should be checked immediately when this happens.
Have you ever let it idle and performed a "wiggle test" of the various harnesses in the engine bay?
Doesn't take much. Shouldn't be fluctuating though. I'm thinking something else isn't right.
I'm gonna have to bail here in a bit.
Was your distributor off at all when you checked it for indexing?
We'll discuss that later. Get that plug out and check the adjustment on the throttle stop first. Post 14. Be sure the butterfly isn't digging into the bore of the body.
So, runs great now but just low idle?
While you've got the throttle body off, check to see if someone ever messed with the stop screw.
Also, remove the blind plug on the driver's side of it with a small pick to expose an adjustable air bleed.
