I hope the theory that they fail early is right and that I'm past the danger......but I'm still checking the oil.
Still a question of how many did fail.

They explained that the PCM somehow caused too much pressure on the injectors causing the wear leading to failure (of course this is a conversation from a year ago, so???).
I noticed no performance issues after the reflash, but I only drove the truck 100 miles before the work was done.
Was this reflash from May of 2003 a bad one? I know the new one is a problem and the same tech advised me not to get it. I have none of the rough idle, surging, smoking, hard starting stuff guys talk about. Truck runs perfect!
