    correct, only 12. waiting on pressure gauge to show up to test fuel pump in conjunction with my vac gun to test against pressure reg and finally monitor system pressure while actually running and actually stumbling.

    yup, full signal contact from pcm to ect as when comes up on temp it drops out of closed loop yet will miss irrelevant if in closed or open loop.

    only code recorder were 14 and 12, 12 only indicates pcm is in diagnotic mode and communicating correctly, 14 is ect issue. Tested not found at fault but swapped out anyway. Erased codes, started, brought up to temps and through the rpms, still has miss regardless of rpm band, cold or warmed up...

    update, replaced with new plugs, mild improvement but still surges up and down and misses, starts, comes up to temp, once comes off closed loop, pulled codes, none only 12, so swapped in new ECT for the hell of it at this point, no change. Once warm ran it up to 2500 rpm, no problems spooling up...
