Hi,

Mine is 1998 totoya camry crossed 102K mileage. While drinving in the highway the timing belt gone, since I don't know much abt the car and continuosly drove the car for another 5miles, it spoiled the one of the 4 cylinders. One cylnder is not working now, and changed the timiing belt and water pump. Car is running, but engine light glows and shakes when it it is standstill.

Could you pls suggest me what can I do now. If repair the cylinder, how much it would cost? Pls advice me.
