Check engine light comes and go
I have a 2000 Durango 5.9 4X4. here's the problem?. the CEL comes and go, code is P0306 (misfire #6 cyl) The dealer replaced the cap and rotor, wires and spark plug. the CEL went away then came back, then went away. Sometimes it's on then disappears. What could be the problem?. Appreciate any help.

check your plenum gasket for a leak
to do this:
take off the air hat over the throttle body, open the butterfly valve and shine a flashlight down the throttle body, if you see oil pooling in the bottom replace the plenum gasket.
