Po141 Po161 Po 304 Po420 . What do i need to do to clear these and will any of these cause the tranny to shift funny? I have to let off the gas to get it to shift and also when it goes into overdrive it seems to drag now. Help Sir expert. :redneck:
Will my cat being clogged cause the o2 sensor codes? So my guess is that the 4th cylinder miss is also the reason for the cat to be clogged.

More than likely it's the opposite. A bad O2 will send too much fuel thru the engine, causing unburnt fuel to exhaust. That fuel will 'burn' during it's trip thru the catalyst convertor, causing the 'cat' to melt internally, which clogs it.
A 4th cyl miss will also send too much fuel into the exhaust.
Either way, you need to fix all three.
Although some backyard mechanics have been known to 'clear' a clogged cat.
Got a leak down tester....you may not be getting any boom out of that cylinder. Bad valve or cam are pretty common to my knowledge
Ok so i still have the problem......I replaced the plugs...wires.....cap...rotor and injector in the #4 cylinder. Still missing. Im getting burnt out here. What else could it be. Dist????
