Forgot to add, the truck currently has about 118,000 miles on it.
I don't think the injectors are bad, as I have never had a lack of power, but the reason for replacing the cups was because about 3 days after changing the oil/filters, etc, we noticed a puddle under the truck.
At first we thought maybe the oil filter wasnt on tight or that the fuel filter was loose.....upon closer inspection, we noticed that the coolant reservior was overflowing, not gushing, but definitely causing the puddle.
Hubby emptied it, thinking he had added too much coolant/water...
The next day, it was overflowing again..........this time he looked in it and noticed that it was diesel fuel in it...
He took the truck, against my wishes mind you, to the local repair shops that works on gasoline motors, who also know nothing about diesels....
They told him it was a cracked head, at which point he was about to have a cow! Meanwhile, I went to TDS and found out what the problem really was and was then pointed to Powerstrokeshop.com to order my parts, at a very nice savings over the local guys around here... I ordered my parts on Friday, and had them by Wednesday, the week before Christmas.....
So now once he gets everything back together, I will let you know if it is running better....
I am still eyeing those Stage 1's.....
Hubby did find a loose wire in there that either goes to an injector or a glowplug, he hasnt figured out which one just yet....
I would hazard to guess that I visit this forum at least everyother day and read, read, read to learn learn learn..
Thanks for sharing the wealth of knowledge to us fledglings out here!
