I still have a hesitation in my 94 EFI Toyota truck.?

Question

I changed my wires again, new plugs, new fuel filter, ran cleaner through it after changing filter, well I drove it to the store first, then put cleaner in it, sprayed carb and choke cleaner in throttle and even in the first part of the air intake hose above filter. I have cleaned EGR Valve and unplugged the top rubber line off of it to bypass it. Maybe I should take it all the way off and plug all the rubber hoses???? I have did everything that I know to do. It hesitates at real low rpm or at a slower speed in a higher gear. You can tell something grabs it and just wont let it go, but you can downshift to lets say third gear, punch it, and man it runs like a jet, well figure of speech, but you can feel a big difference. What can this Be????? Please, educated guesses, I need it fixed.

Answer 1

Could be rear end trouble in your pumpkin or O2 sensor problems

Answer 2

consider testing the Throttle positioning sensor, its signal is also used by the trans.
