Bogging out over 3k rpms, no power...

The car seems to bogg out most of the time after 3k rpms. and it seem to act up more often the longer i run it during the day. it will start to misfire and lose power to where i have to keep letting on and off of the gas just to keep it moving.(mind u at this time im only goin 5 mph). when i let it cool for a min. it runs ok but then back to the boggin out thing again. computer shows i keep getting a misfire in cylinder 4 and and O2 senser. i have changed the following... dpfe senser, whole egr system, plugs, wires, coil pack, O2 sense. after market air intake, aftermarket headers and downpipe. i have the bogging less often and can finally tac out over 3k rpms, but it is still acting up the same. can i get some help

1994 Toyota Tercel, Low power at lower rpms up to about 3k I'm guessing seeing as how I have no tach; picks up a bit after 3k rpms. Also runs rough at idle after it warms up. Cel code 25, I have replaced...


if the ignitioin system is ok and not in need of replacing, I would venture that your catalytic converter is plugged. Had similar issues with a Chevy and that was it, when you drive for a few minutes, then pop the hood, will your exhaust manifold flash fry an egg? is it red hot? then replace the converter and have a nice day. this would also foul your O2 sensor.
