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.
have the same problem?
