I am dealing with this prob. going on for 3 months! Glad I found you guys. Ive got a 1993 toy 2wd. 22Re put a fresh engine in went to an electric fan (just for a/c IN PHOENIX) anyway after about 300 miles that darn fan quit and it got a little hot since then it stumbles unless you have the pedel to the metal.
Had to advance the timing quite a bit just to get it to move! when timed properly it coughs out of the intake. Changed the head gasget just as a precaution and no change. burped it to many times to count adjust the tps no change. what am I missing????? Thanks for your suppoort.

 

bad ECT sensor maybe

 

When you say fresh engine, what do you mean? Was it a rebuilt engine? Any machine work done? When you replaced the head gasket did you check for warped surfaces?

 

had the head checked all is good there. it didnt get THAT hot boiled over Sitting at a drive though when it happened shut down right away. the engine was rebuilt at a well known shop.

 

checked the ect checks ok rechecked the tps. Im missing somthing! it gotta be somthing simple Im missing

 

Rebuilt...You pulled a 22re and had the same 22re rebuilt? Reason I ask is this....If it was a rebuilt 22r the timing is set differently than a 22re....Not trying to insult your yota intelligence, but you said "something simple."

 

I bought a fresh rebuild 22re to replace the 22re I had. The new engine ran GREAT untill it got warm. now like crap. I think after some investigation I think Im gonna have to bite the bullet and take the head back off. and go to a Toyota gasket. Dont want to!!
