So I'm trying to figure out what's causing my 22RE to stumble. It will kinda bog down on acceleration, usually around 2100 to 2700 RPM or so, and it will do it in all gears. Sometimes it will pull fine, then the motor will bog down and kinda struggle through that RPM range. I've changed the fuel filter, the TPS, and AFM. Oxygen sensor was also recently replaced after codes 5 and 11 showed up. Timing was fine, but I have it a set at 8 degrees shorted. TPS was set per FSM, but ran real bad, bogging out a lot. I adjusted it so that it had continuity with a .85mm feeler gauge under the throttle stop (instead of non-continuous) and the bogging didn't seem as bad. That's how it's set now - any of ya got suggestions on where to look next?
