Ok so I am having some serious misfire issues with my truck(2006 1500 SLT 5.7) I have replaced all 16 spark plugs, check the voltage from the battery and alternator and even replaced the thermostat( dude from advance said the ecu may not be reading that the engine is warm and cause it to misfire) The weird thing is that when I'm at full throttle and rpms are above 3500 it runs like a champ, so I'm almost at the point of taking it to the stealership. The only other issue I'm having is the typical headlamp going out from the fcm or pdc, could the misfire issue also stem from this?? Any help would be GREATLY appreciated!!
