I think I may have the wrong or bad water temp sensor.
Runs awesome when first started and warms up, but after everything heat soaks (30 min or driving) it lacks power and seems to heat the exhaust up as the temp gauge stays normal.

Reading how the ecu changes the a/f ratio as the temp goes up, could it be like the choke it stuck on a carburetor engine ?
Or more likely the air valve under the TB the water lines go to ?
I've unplugged the other air valve and nothing changes.

Seems I've got it just about right but when actually driving it longer I still have this problem.

I assume the JB-Weld and or block off plate for the TB is what I'm going to try.
Been talked about before but I "think" the block off plate for the car will fit the montero ?

Also.. could I splice in a rheostat into the water temperature sensor and tell the ecu what I want and what runs the best at the time ? I don't think I got the right sensor, same plug but could be a different ohm ..
Factory supposed to be 2.5k cold and 290 hot.. from what my manual says.

Did a DIY block off plate for the throttle body, every runs great now but still gets a bit sluggish after warming up.
Assuming it needs the proper temp sensor. Even if it's one for a Chevy, as long as the ohms are the same I can cross thread it into the housing and JB-Weld it from the inside.

Just need verification on the actual ECU sensor and not the A/C switch that the parts house sold me.

Buy the proper sensor online, Rock auto or anywhere rather than Fing up the system.

Try and find one.. no one has the sensor that's actually listed as for a 1990 Montero..
It's the front facing one with white plastic, 2 up right ribs on top, 2 angled out and down on the bottom. 2 pin.

I ordered one for a Mitsubishi 3000 GT but of course has a different plug but comes with a new one, but it's a STD 3/8 NPT not the metric unit. I'm gonna get an adapter that splices into the upper radiator hose.. problem solved and off the shelf unit can be used, just not the one it calls for...
Most all units run about the same Ohm range, mostly the threads and ot plug is different.

But she is running awesome, very smooth. It was the o2 sensor wire up by the transmission shorting out and old injectors. So I'm almost got it running perfectly now. Hope a new sensor clears this up and I'm ready for a trip to Ocala National Forest for wheeling and camping.
