Hey all, just got my first Mighty Max. Solid vehicle for the most part.

Truck info:
1994 Mighty Max, manual, v6, 150k miles, 4x4, in Alaska

After driving a little bit it will stall after going into neutral.
When it is restarted in neutral it will idle fine until driving and going back out of gear.
Things we've tried:
-New idle air control valve
-let idle for 10 minutes to try and reset ecu idle
-checked for vacuum leaks
-cleaned the mass air flow sensor
-reset throttle sensor to .45v at closed

The check engine light isn't on so I don't think it is throwing any codes.
Any suggestions on what else I could try?

Side note:.
Windshield wipers quit working. Multi-meter doesn't get voltage from the plug in for the windshield wiper motor. Can't figure that out either.

Cheers!
