This is why you need to use a trusted mechanic...

I see/hear stories about, stuff like this often...

A money hungry mechanic will actually perform the unnecessary work changing an intake manifold (or not and say he did) and in an instance similar to this, change the fuel filter which was the problem in the first place...

Or maybe he knows what he's talking about and is correct in his diagnosis... I don't know how long he had the truck or what tests he performed to come to this conclusion...

I've told friends to mark parts and make sure they were removed and not just shined up and caught people in lies this way... I have never brought a vehicle to a mechanic because I trust no one! Haha

 

Im right there with you. I would much rather ask questions and do it myself.
