When engine is cold it surges (not like a miss) for about 2 miles. Then it immediately stops surging and runs very smoothly from then on. No engine light on. Does not feel at all like a defective plug coil as I have experienced that type of miss on several occasions when different coils have been defective over the life of the car. What causes the surges?
