Engine

Vehicle Information: Model(924/944): 944t; Year: 1986; Engine (type, size, modifications): 2.5 turbo still modifing; Total Mileage: 73880;

The car starts great but has a lot of vibration when cold. When it warms it isn't bad the car runs great. It has new mounts, the belts replaced 5000 miles ago. Also a new head gasket 5000 miles ago. Had problems with injectors leaking off replaced them and the replacement injectors and it ran rich. Had the old injectors redone. The car is smooth off idle. Also has new TPS. We had a rain a while back and the water was deep. The water was oil pan high, and I blew a cam box gasket (cold oil). Could I have knocked out a sensor? I have 16" to 20" of vaccum at idle when warm and 10" to 12" when cold.
