Hears the deal; this all started when I changed the spark plugs. Truck ran fine I was just doing pms. Changing the plugs ended up with having to rethread one of the coil pack bolt holes in the intake. One that was repaired I installed new upper and lower intake gaskets, torqured everything to specs, installed 2 new coil packs (broke 2 getting them out), replaced all 8 plugs with ngk oem replacements, buttoned everything up and to my suprise this lopeing and sounds like intake backfiring. Please help! Engine is a tritron 4.6
have the same problem?
