My car is intermittantly falling on it's face (bogging) @ roughly 3k RPM... in any gear, can be while crusing, while accelerating.
i.e. accelerating from a stop, bogs at 3k.
i.e. crusing at 3k, part throttle on & off, and then suddenly starts to bog.

I tried cruising at a higher RPM, i.e. 4k RPM and it bogs at 4k intermittantly. I didn't take it much higher than that in to reduce any damage it may cause.

If I pull over, and restart the car, it drives normal for a little bit, and then will do the same thing again. While cruising, I just key on & off real fast to reset it (like when you're tuning and have the reset the ecu for updates) and it will drive normal again, but only for a little bit.

I changed out one of my injectors yesterday (used) because it was leaking fuel onto my intake manifold. Could an bad injector cause something like this to happen?

Any help would be appreciated.

One more thing, I am receiving NO CELs.
