Whole bunch of codes...

P0302 cylinder 2 misfire

P0300 Random/multiple cylinder misfire

P0133 02 sensor circuit slow response bank 1 sensor



I put in new spark plugs and new spark plug wires and the P0302 code still pops up (and now the P0300 code pops up, which didn't happen before). I also installed a new 02 sensor in the rear and the old 02 code disappeared but now the one above shows up.

Does anyone have any idea how to fix this? It's driving me insane. :nerd:

I am not sure but IIRC the 3.4 uses dual tip plugs. Did you use OE style Denso or NGK's?

I used NGK's.
