Truck has been balck smoking for weeks now . took it to the shop and was told that i needed to have the MFI Injecter set replaced with a new one including a new fuel pressure regulator . Did that to day and the Darn thing is still black smoking and smelling real rich . Anyone know what else could be wrong .. Maybe replace the plugs since it has been running like this for a while prior to replacing the MFI.
no Check engine light is on and computer not pulling any codes.
Thanks for the help :)
.
OKay so i pulled out the plugs and the were solid black so i cleaned them up and checked the gap to make sure it was .045 gm spec . put them back in started it up ran fine no black smoke till after i drove it around and it warmed up to 195 came home put it in park and there it was the black smoe and rich smell .with a slight rough idle and i mean slight idle is right around 500 rpm 's any ideas.
