I picked up a 1994 Toyota pickup with a 22re in it that I just can’t figure out, the truck will fire up and idle pretty smooth but anytime you give it about more than 10% throttle it just hesitates and wants to die, but if you ever so gently give it throttle you can get it to rev up. So far it has a new TPS, AIR FLOW METER, FUEL PUMP,ECM. From here I’m not sure where to go with it any insight would be appreciated thanks,

 

I had a similer issue that started out of the blue. Went to drive my 87 one day and it would try and die with just about any throttle input. Ended up working it down to the mass airflow sensor. I'd check that. See if it makes any difference.

 

Have you looked for any vacuum leaks? What is the condition of the throttle body is it very dirty?
