7.3 Blowing To Mutch Black Smoke??

[Kelleyj1837]

My truck that i got about a year ago was rolling coal when i got it and still is. At first i thaught it was cool but know the gas milage kinda sucks. getting like 8 MPG everywhere i go is getting old. Also it is verry slow almost like the engine has to mutch fuel. So i take it some one before me tured up the injection pump a little to mutch. So is there a way to retun it to stock postion?

Yep, you can decrease the amount of fuel just as you can increase it. I would look into having your truck timed as well, that could help in the mileage department. I hope you have a pyro, rolling coal like that can get an engine hot in a hurry. Good luck.

Is it a turbo? How's the air cleaner?

I would double check for restrictions in the intake and if turbo make sure boost is up to spec, if these check out good then find the adjustment article and follow it, but instead of turning the screw clockwise, turn it counterclockwise
