Yes my cobalt is misfiring so I think that's what it's doing only does it after

fuel pump injectors plugs coil packs throttle body catalytic converter timing
chain most of the sensors ecm I've done a Compression test dry and wet all
cylinder were right around 170 to 180 fuel test holding at 50psi any guidance
would be appreciated thanks in advance
