Thanks Rick & Tank,

Steve Brotherton was kind enough to refer me to a Tampa shop which I will check out in the nexr few days. It is very difficult for me to get to Gainsville to see Steve for a variety of reasons but it is great to know about that option.

In the meantime someone else on this forum recommended a shop in St.Petersburg by the way of Whispells and I went by there today.

My problems are intermittent rough idle and injector knock that started with replacing the seals on the pressure valve holders on top of the injector pump.Whispells said my problems are likely a result of worn out injector tips and he wants to start there. He contends they are only good for 90K miles, mine have 146K on them. I was very impressed with Mr. Whispell and it is an old timey kind of place. He works on Rolls Royces too and there was one there when I was. He says he has the necessary Bosch test equipment to do the injector job right.
