So I have a similar ish problem and am new to the site but CAN NOT seem to find my specific problem.. I have recently tried to put in the 205 tips myself. I bought really poopy tips from a 3rd party, online, 60 bucks for all 4 kinda thing... it would start and run fine, then would seem to drop a whole cylinder or TWO off. it would shake tremendously but still stay running. give it throttle it would work out fine. noticed my glow plug light was flashing at me, so I assumed I had pulled too hard on the wiring there? it all seemed fine. I had decided to take them in to the shop that does all of our nozzles for our CAT engines. The tips were so bad out of box they were leaking passed the poppet valves or needles or what have you. Not one hundred percent sure on terminology on these guys. Bit the bullet and bought more tips (same as a buddy is currently running) and handed them over to all be balanced. Randy at Diesel Specialties says they cleaned up hundred percent better!!! So, I head to NAPA grab another new set of copper washers and throw everything together as clean as I am capable of in my home garage. Crack lines gets everything running and make sure everything is tight and she purrrrs.... after a few short seconds of celebrating I was cut short by the same symptoms erratically shaking engine and blinking glow plug light. Hop back on here again after a few hours of feeling like kicked in nuts for spending so much on my FUEL SAVER!!! And I find someone saying blinking glow plug light due to brake light out. So, turns out, 3rd brake light is super dim when I hit brakes. Basically I've seen a few different websites talk about a brake light out possibly causing these symptoms but never did it before and my light isn't out. If someone could enlighten me on how all that is either connected or if I am even on the right track here? please please please PLEASE help me out haha. THANK YOU SO MUCH IN ADVANCE AND IM SORRY FOR THREAD JACKING... << just closest thing I have found with recent replies to boot...
