it is manual trans. i replaced knock sensor today it was cracked. I started it up and it ran rough and was cutting out and stalled. when i tried to restart it it would just crank over and could smell raw fuel coming out of exhaust pipe. after 3 or 4 long starter runs it started to skip, then it 100% started and ran like nothing happend? I had constant fuel pressure while this was all going on also. I thinking maybe the ignition is cutting out? I have get codes rechecked tomarrow and see any new problems showed up? it is manual trans. i replaced knock sensor today it was cracked.
