Went to AutoZone today to see what was causing the CEL light to be on. Their code reader said it was
P0306-- Misfire in the no 6 cylinder. So what to do now??

Alittle history on this 97 Rodeo. Just put 2 used, but cleaned and checked Heads on it. New Timing Belt, New spark plugs.

Could it be as simple as the hookup to the coil pack not working quite right? What are things to look for?

TIA
