I really appreciate that the guys at Auto Doc are conveniently located, trustworth and friendly. The only thing that I would have liked to see is a more complete diagnosis done on my truck. I believe a electronic computer test and visual test were completed, but I would guess a road test was not. If a road test would have been done they would have noticed the vibation in steering wheel and the "cutting out" from the engine upon acceleration. I told them I'm going on a long trip and asked for the truck to be evaluated and repaired. They did a great job on the items that were diagnosed and were very speedy about it, which I greatly appreciate. However, driving home I quickly realized the two items I mentioned above were not fixed. I would like to be clear and say I didn't mention the vibation in the steering wheel when I dropped it off, but the cutting out of the engine was mentioned and the dianose was a "carbon treatment would make the truck more responsive". The carbon treatment did increase the responsiveness, but the engine still cuts out from time to time when accelerating. I'm hoping those two items will not be a major concern as the budget for the repairs has been used up on the orignal trip to Auto Doc. I will be going back to the Auto Doc in the future, but I'll be a lot more specific about what I would like to be looked at rather than a general evaluation of the vehicle. I'll chalk this trip up to mis communication as I can see how I could have been more clear in expectations when I dropped off the vehicle.
