well hooked the ol'scanner to the car today and its giving me codes for random/multiple misfires and a code behind it for o2 sensor low response. anyone know what i should check out to fix this?

I had that problem once, turned out to be crappy fuel, so i pulled plugs and cleaned them up a bit put them back in and went to another gas station havent had the problem since.

replace the o2 sensor.. then see if the random missfires go away.

i might do that, wonder which one it is though? i personally havent seen any misfires, i was a few weeks ago but since then the lights came on when i havent noticed any misfires. so just clean up the plugs and change the o2 sensor and i should be good?

what was the number? I wanna think 1134 or something like that was the first one in the manifold, it says bank 0 (or 1 depending on reader) or bank 1 (or 2 depending on reader).

yes change the o2 sensor, its fairly common that o2sensors start to "slow" down over time, I actually just had to do this to my stock cav (minus the exhaust)

I was gonna say. Low response, or SLOW response.

Slow response will be the first O2 sensor. The 2nd one is supposed to read slower.
