I have a 2006 Chevy 3500 van with the Vortec 5700 that died. The place they towed it to replaced coils, plugs, MAF and O2 sensors. Now it starts immediately, has a P0300, and shakes/runs horrible from idle through upper RPM. Coolant and oil levels were normal. In/out of gear made no difference.
Is someone able to page through this log file to see if there is anything obvious that was missed? It will be quite a road trip for me to go look at.
