Thanks for your help, Jim. Everyone I tell this to thinks the same thing. This shop is actually the largest Ford dealer in York. They worked on it for two days both times I took it in. The shame is that it ran great before I took it in although the engine light was on. They said that the bolt had oil ports in it which caused the repair difficulty. Maybe my description is not complete. Now the light stays on becuase of the oil on the oxygen sensor. They offered to replace the engine for about $2,100. I theatened action but they claim there was nothing else they could do with it. I don't suppose you could recommend anyone around York, Pa.
