Hope this isn't a sign of things to come on modded '03's:

Bad news for all? Probably not. TOMMYGUN had just had the head swap done and it sounds like the dealer screwed something up. Maybe the mechanic dropped somthing into the cylinder and it damaged the rings.

I'm sure that Ford has a lot of competent techs who can handle the job. I'm also just as sure that there are some who can't. It's gonna have to tick like a mofo before I'd let the dealer loose on my engine.

You should have seen the techs face when I rolled in with a cloud of smoke behind the car, every tech in there looked at the car then the guy who worked on it. PRICELESS

BROKE7- my car only showed some signs of detonation after I picked it up from the cyl head replacement. That was with the chip in or out. It would detonate a bit on the 3-4 shift and then the top of 4th so who knows

lol, I bet something was partially clogging the injector. I hope you stocked the car back out before taking it in there and suddenly forgot what a chip does or where it goes.
