Injector Problems - Help

TxToyMan · 07-15-2007, 12:57 PM

I have a 2006 Dodge Cummins W/ 6 speed Manual. I change the fuel filter every 12 - 15000 miles (every third oil change). I use the drain valve at each fuel stop (on the fuel filter housing) for 2 seconds, and I only purchase fuel from major truck stops. The truck has 110,000 miles. When at idol, the truck runs rough, but runs fine at any speed. The dealership told me that the number 2 and 5 injectors were bad, so I had them replaced but the problem is not any better. Now, the dealership wants to replace the other 4 injectors and clean the complete fuel system. (about another $3,000.00 ) I am questioning if this will really fix anything or just spend my money. And if it is the injectors, is there any other fuel / water filter system that I can ad to help prevent this problem?

Are they sure it is fuel related and not air/vacuum?

sounds like a simple pressure problem to me. Have you put a gauge on it?
