How much of a service would it be if I offered to save non working AFM from the 3.0 V6. I thought I lost mine but after finding out the replacement cost I found some of the weak points and rebuilt it now my truck runs like a champ. It's not a task for your everyday person there are very sensitive components inside thats why I would offer to do it as a service as oppsed to a tech write up. New ones are $500 + I could do it for a $100 or so. Just a thought. I dont know how often these things go bad but when they do who the hell wants to pay $500 bucks. Let me know what you think.
