I have a 94 chevy 1500 with the 5.7 350 i recently noticed the truck smoking s lot in the way home from work one day it hasn't done it at all before and checked the oil it was a little low so i topped it off. get home and it still didn't quit smoking so i notice it is only coming out of the drivers side exhaust (i have true duals) and i decided to change the plugs after i change the plugs i put the wires back on in the firing order they go. it run like ****. so i decided to pull the intake and the drivers side head to see how it all looked. everything checked out okay cleaned all the carbon off put it back on and i'm still getting the same problem. it backfires boggs isles really rough like i has a big cam. it seems to me like it's out of time or a wire is crossed but i have checked checked and triple checked following the firing order. someone please help before i go pay someone hounded to look at it
