Fixed my month long battle of misfire cylinder 5
Symptoms: rough idle sometimes
Clean acceleration
Loss of gas milage
Smoky exaust sometimes
Loss of oil and oil in air cleaner
High idle problems or inconsistent idle
Code 305
Rich smells at idle
Ticking on acceleration sometimes
Tried: plugs,wire,coil,IAT,new throttle body,TPS,vacuum leak tests,combustion leak tests,compression leak tests, tested all wires and sensors in engine area....

Huge split in lower intake gasket in between cylinder 5 valves..it made all symptoms go away..runs like a new truck!
