Is my car's timing off?
Every engine is a little different, to be honest, but most just will not run at all if the timing is off. Others will run really badly. Unless something has been done to the engine leading to your suspicion that the timing is off, it would be quite unusual for such a thing to develop on its own. If so, you really need to get the car checked by a good mechanic as soon as possible to minimise potential damage.
