Rig started cutting out a little around 1800rpm. So I put the the fass 150 in ran it about 8 times and the cutting out seams to be getting worse. Now its doing it at 1500-1800 rpms. I got around 6 tanks of fuel off the job I was on hadn't had any problems until I used it. Reading codes p1693 and p0230. thinking the fuel was contaminated and is there anything I can do to clean this out of the injection pump? before I put on the fass 10psi at idle 5psi at full throttle.Help!
