I cleaned the MAF sensor this morning with electrical cleaner. semed to help some, just smokes black when its first started for about 5 min and the while under slight exceleration, not sure if the fuel milage got any better, working nights and not had any time to go anywhere, i am also going to try cleaning the map sensor and the iat sensor, and see if this will help. i have a nabor that said he can check my injectors for me, but he is working this week, mabey this weekend i can get them checked and make sure that they are good.

you need to make sure about an injector Asap. you dont want to drive it and melt a pistons with to much fuel. I believe this is correct info

I cleaned the map sensor, it had some black on it. It has goten better, not smoking as much as before, mabey a min or so at start up and then it still smokes under slight exceleration. not sure if this is normal or not, does it with the programer on and off the truck. Is there an easy way to check for a boost leak?

Bad fuel possibly...

Have you checked your oil level? See if its creeping up or smells like diesel fuel.

"From: DBLR
Have you not read where it is not advised to use any fuel additive that has alcohol in it unless you are using it to de-gel your fuel? Yes it may clean up your injectors and clean some carbon but it is not good for your fuel system and can even hurt it. To sum it up I’ll copy what DD had to say in another post about it “Fact is that alcohol kills lubricity, and that is the last fuel additive that should be used on a diesel.”

Next 2 quotes are from: DULUTH DIESEL
Alcohol kills lubricity. Every major additive manufacturer, including the stuff that Cummins puts their endorsement on, know that alcohol is a bad deal for diesels. You are not doing your engine any favors using SeaFoam. There are better diesel fuel additives that do not use alcohol.


To be fair, SeaFoam itself isn't a bad product. While it is widely known that alcohol has no place in a diesel fuel due to lubricity issues, I have used SeaFoam in gasoline engines, especially small engines, and have had good results. The only issue with SeaFoam in a diesel application is the fact that there is alcohol in it."
