HMM most definetly not normal. I dont know what to tell you to check being that it is an LMM. Your injectors should be fine. Just to make sure check your balance rates using EFI or a tech II. Have you checked your coolant level lately? Just to make sure it isn't leaking coolant.

This very well could be true!! I didn't think of that. If it is trying to regen you need to use you programmer again to be sure that you have regen turned off! If not and it smells sweet my thoughts are turned to headgasket but why would a truck running a 90hp tune lift a head?
