you might have a leak in the lower intake manifold or the upper air tank plenum . i had a leak in the upper air tank plenum when i took my fuel injectors for servicing , when i put the plenum back on i missed some old gasket material and that allowed a leak

 

i already checked both of those and all vacuum hoses with starter fluid while running and found no leaks

 

That is true. But in 1984 when toyota first put EFI on a 22RE it was an analog EFI set up, which is a different set up than what is used now. In 1985 toyota updated to a digital EFI system, and thats whats on the 22RE now.

Do a google search to learn more about the analog EFI.

 

thanks myyota, I didnt know about the analog EFI , im looking it up now , interesting

 

I would recheck your tps adjustment. Does the idle drop when you jump the test connection? When i got my pickup, I checked the ignition timing to find it was set at like 25* btdc. Set it to 5 where ts supposed to be and couldnt hardly go 40 mph. I had no idle drop when jumping the test connector. So i adjusted the tps a lil after doin research and got an idle drop. Then i set the timing to 5* and its now the best running 22RE ive ever seen. Worth a shot.
