P0300 misfire code... data info included
getting a random misfire code... here is all my infor at idle (doesnt really misfire at idle)
02 b1 s1 - between 1-850 mv (bounces around, normally says up in the higher range 500-800)
02 b1 s2 - 443 (PCMFORLESS)
02 b2 s1 - between 1-850 mv (bounces around, normally says up in the higher range 500-800) follows the 02 b1 s1 oxygen sensor pretty much
02 b2 s2 - 443 (PCMFORLESS)

MISFIRES after a short normal drining run, with a few revs (reset scanner before run)
1 - 4
2- 1486
3 - 0
4 - 0

I can really feel the misfires down low like between 1000-2500 rpms
I have new plugs and opti.
