    Hook up a scanner and moniter your front o2 and see how it looks. Replace the coolant temp sensor on back of the head. Check for a plugged cat. Just a few more ideas to look into

    I will say that the Royal purple fuel atomizer treatment in the small bottle works great. Has really helped my truck run better than ever.
