I have an 03 3500 I just purchased and it was showing signs of the lift was going out. Last night I put a FASS pump on and it seemed to fix it part of the problem. The only problem that still is there is the fact that it runs rough for about 1 minute or so after starting it for the first time of the day. After the initial startup it will start and run fine the rest of the day. I should mention it was doing this BEFORE we installed the FASS pump, but it didn't seem to help.

 

any white smoke when it is running rough??

 

No white to mention, something I just remembered, besides the FASS pump and straight pipe the engine is stock

 

I went out to start it this morning and some light came on, I did the 3 key thing and the code P 0341 on. Found out this is some kind camshaft misalignemt. It is still running fine but WHAT DOES THIS MEAN.

 

sticky injector/s run some power service in your next tank
