2006 k2500 reduced power 

Good catch. I don't like to throw parts at a situation either. It's a lazy (and $$$) way to attempt a repair.

I had a 88 2500 that would not start. I thought I knew a good mechanic. I paid him 200$ and he couldn't tell me nothing. I scrapped it, next day my truck running like a scalded dog. Dammit
