So, I have been dealing with some bad injector issues for a little while now, in May I purchased 5 new injectors and the van ran better, black smoke was eliminated, and I got better fuel mileage.
7,000 miles later I began to develop some smoke at start up again, and a bit of a gallop to my idle....
I checked the smooth running at idle and found the #2 injector to be the culprit, I swapped in one of my old ones and things got notably better.
I have replaced my fuel filters more frequently than the manual suggests for the last 100,000 miles, I replaced the fuel filter about 100 miles before I replaced the injectors, and I've always been meticulous about cleanliness when I have the fuel system open in any way, a full pressure wash of the area where I will be working....
So, it seems like I have fuel contamination issues, so I installed a Caterpillar 2 micron fuel filter downstream from the stock filter, I have now driven about 200 miles with that set-up and want to get my already failed new injector rebuilt, so I make some calls and find a place in Texas that offers a 2 year warranty on their rebuilds and they reuse only the body of the injector, every orher part gets replaced, great.
The guy says the problem is debris in the common rail, and insists I will continue to have problems if I don't send him all the connecting lines downstream of the HP fuel pump, so all 5 injector supply lines the line from the pump to the rail and the rail itself. He cleans them all in an ultrasonic acid bath.
So, my question is how does debris get into the rail if the only thing that has ever been in it is filtered fuel?
I did have my HP fuel pump rebuilt by Andy Bittenbinder about 6 years ago, I suppose there is a chance that material is coming from the pump, but I'd expect that to be somewhat catastrophic which is not what I am experiencing.
Anyone ever get their fuel rail cleaned?
Should I just get the #2 injector rebuilt install it and see how it goes?
The van is a 2003 with 175k miles on it...
