Hi
Make sure you check the Wiring harness.
I had the same problem to where nothing would fix anything and I found a wire broken inside of the insulation from the temp 2 sensor to the ECU I checked
all the pins and all the ohms for all the items and everything checked out ok. But never checked the actual wire. Found the wire to be broken internally.
spliced in a new wire and the thing ran like it always should have of course after replacing a ton of parts that where not bad. I actually bought 2 vanagons
and parted them out to use for parts for my vanagon to find out that a simple wire would have fixed it long ago. I even rebuild the motor and fuel injectors
along with any and every sensor and hose that could be changed I changed it. Still was just the simple little wire. The wire was ONLY 22 years old go
figure.
