with all th einjector failures there have been in these trucks I wouldent be surprised if they tried to get out of another one. I have personally seen STOCK trucks with failed injectors that had internal engine damage denied warranty because of suspicion. chrysler is a sneaky sleazy company if you ask me, and get out of whatever they can.
i had a customer that was denied warranty because his cylinders were worn? chrysler never even pulled the bottom end appart, they said there was excessive space between the piston and cylinder, without pulling them and measuring them! the customerowns a machine shop and insisted on coming down and measuring the cylinders with a dial bore gauge and measuring the pistons after getting the specs from me. and they wouldent let him, denied all warranty, and made him pay to reasemble his truck to take it to someone more competant shice he was paying anyway.
