**THEY WONT LET ME USE PUNCTUATION SORRY I'm a self taught mechanic going to school soon for auto tech What is causing my p0306 code in my 06 durango it's a 47l i know its the misfire code the cylinder has good compression coilpack is not bad. replaced spark plugs 2 times no difference poured atf in the 6 cylinder 2 times and it took the code a longer time to come back I have cleaned the throttle body I have cleaned the air filter I have switched the coil pack so i know its not it fresh gas fresh oil change im starting to suspect the valves or the fuel injectors i read on another site that the valves in that cylinder go out frequently on this engine but the fuel injectors tick loudly at startup and until its warmed up i know its the injectors because as i give it gas it goes faster too the truck runs great when no CEL but as soon as it comes on it starts to idle odd its not a terrible idle surge its like maybe 100rpm variance and shake a lil but when you gas it it takes off still WHAT IS THE CAUSE? **
