I have a 22 RE pickup I recently purchased. It hadn't ran in over a year before I bought it. I drained the fuel tank and replaced fuel filter and got it running. Had cel for bad AFM, replaced it with one from NAPA. Codes went away, starts ran great for about 80 miles. Now it intermittently stalls while driving. It will start right back up and run fine. Doesn't do it every day, checked for codes this morning and none showed up. Anyone have any ideals?

Thanks for your help.

 

Coolant temperature sensor?

 

Man I think your right started watching the temperature needle and it does occasionally do a quivering think. Do you know where this is located?

 

Passenger side under the air intakes by the throttle body. A YouTube search will help. Easy fix. Get a good quality sensor. OEM or Napa.

 

Temp sender for the gauge has nothing to do with the ECU, there is a 2nd coolant temp sender for the ECU near the front of the intake.

 

Lots of good YouTube guidance.
