My car has been bogging/missing, most noticeably between 2500-3500 rpm, for a long *** time, and I can't figure out the source.

It got to the point to where between those rpms my car would jerk violently, and during acceleration it sporadically feels like it's missing and bogging throughout the rpm range.

I've replaced:
dizzy cap, rotor, plugs, wires, fuel filter, air filter, ignition coil, tested a good tps, checked timing, etc

When the jerking got extremely bad I replaced the plugs and it seemed to help the problem a lot, but its coming back as usual.

Also it's thrown codes for random misfire in cylinder 1 and 2 twice in the past year, both times while starting the car on a hot day.

Nothing major, car runs, just annoying. I'm putting together a turbo setup and would like everything running how it should before I'm boosting.

Any other suggestions? I'll pay 20 to whoever gives me the right tip. Thanks

Your car will run extremely rich with the O2 sensor unhooked but nonetheless it will run.
