my gtp sc feels like a crapy 4 cylinder and it stalled twice at highway speed and one time when i put it in neutral it started itself back up??? occasionally ill start it in the morning it shuts off a sec later starts back up and does it again. also the engin sometimes makes a loud knockin noise and when i change the oil it stops. i have an evap code p0440. and had a cyl 4 misfire code that went away. i have replaced: plugs wires pcv, battery, alternater, icm(twice) and coilpacks. today i cleaned the maf. im sure im forgetting about something there is so much wrong. im also gonne replase the crank sensor this weekend-pain in the butt. any suggestions? besides getting rid of it, lol thanks
