just bought this truck and it rode fine for 2 days then the third night i started it and it idled rough and gas smoke came out of my exhaust! well cyclinder 4 wont fire and i just changed the plugs and wired and still no fire i need some help

 

Any oil leaks you're aware of? Seems to me like you're cylinder 4 spark plug isn't firing due to probably an oil leak getting into the cylinder causing the plug to foul. Either that or a warped head/blown head gasket. I'd take out that spark plug and see if either oil or coolant is on the plug.

 

theres a small amount of oil in the plug but gasket is fine

 

was it the black one?

 

my truck is white

 

okie dokie

 

The plug that had oil on it, was it wet or was it just black from carbon build-up?

 

barely wet could it be my egr valve?

 

if you had a nickle for every time someone asked you that. . .

 

Doubtful. That wouldn't foul out your plug. Do you smell gas? It'll probably oil on the plug. Try replacing the spark plug tube seals. Shouldn't be in the least bit wet.
