Yep its warranty time03GreyMach1 said:Hi all, I have a weird noise from the engine when its cold, I hear it when I let go of the gas just before a shift.
Sounds like a wrist pin type noise or piston slap?
Is this common to mach1's?
Warranty time? only 26000 KM's

The chevies I had always had bad bad cases of piston slap when the engines were cold.. the engines lasted a long time.. that doesn't sound typical of a DOHC 4.6.. or a 4.6 at all for that matter
I'd get it checked out

One of your pistons is sticking
Trying to find out but its a recall I believe (If its not it should be) Contact KrazyPony on this site.
He owns a 03 Mach 1 and knows about the problem
Def take it to the dealer and get it fixed
