"Had same problem initially with my daughter's '96 after replacing several valves following a broken timing belt at highway speed. The cam sprocket and crankshaft timing marks will align every two crankshaft revolutions so you are probably 180 degrees out. Align the marks and remove the timing belt then rotate the crankshaft one revolution until the marks are again aligned then replace the belt and you should be fine."

this is what one guy says on another site any one explain it to me?
