I do not even know what to call what my vehicle needs. In any case, Dr. J and her gang of highly motivated and talented folks have been trying to figure it out for quite some time. It gets better for a bit and then oops - crappy again. We are to a point of experimenting with all kinds of odd stuff I do not understand. I keep thinking I am done with the truck and then I see the cost of used trucks and change my mind back again. Dr. J and her staff have been nothing but friendly, knowledgeable, reasonable and just hard working great folks for the whole 34 years I have been using their services. Whether or not my old truck recovers and remains usable (the goal), I will always be thankful for the care and wisdom of the JayBees crew!
