high rpm chugging on my 22re...HELP
I'll just give the symptoms and hope someone can help. (the vehicle is an 89 4runner with an EFI 22re and manual trans) It seems to me that the engine is bogging out at higher rpms, right before when you would shift on regular on-road use (I don't have an rpm gauge but i would guess around 3 grand). When this happens it loses all power and i am forced to shift prematurely just to keep it moving. Chugging would be a good word to describe the feeling and sound of the engine. Also I'm getting a massive odor of gas at the time of the chugging. The engine also idles very rough and often very low and the idle is adjusted to the max and still very low and rough. I had this problem before and adjusted the idle and replace an obviously bad dash pot, the problem seemed to be fixed but now is back and the battery light and brake lights now stay on, (not the check engine light though). Ideas? Things I can try? I thought the TPS, maybe a clogged fuel filter, but i really don't know.
