"93 2wd p/u, 22re,5-speed, 230,000 miles just started missing at around 2500 to 3000 rpm, in any gear, runs great up to that speed. Head rebuilt along with new timing set 5000 miles ago. New fuel filter, injectors, throttle position sensor, air flow meter, O2 sensor, plugs, cap, rotor, new Toyota wires, air filter. Plug gap correct, timing correct @ 5 degrees. No trouble codes set. I disconnected the aftermarket tach to make sure that wasn't the problem, disconnected the vacuum hose at the egr valve and drove it, not that....Feels like intermittent ignition miss or throttle position sensor, as I can go above or below that rpm range and it will smooth out. Anyone have any advice on this one? Thanks in advance.

 

sounds like the same thing mine is doing lol and i am so lost... i think its my o2 sensor, i also have the afm code, and my afm seems alright so everything points at my o2 sensor. in your case it sounds like you have replaced everything lol so hmmmm
