You'll damage (probably seriously) the engine and related components such as the transmission and drive-shaft - how bad will depend on how "off" the timing is.
A timing belt failure normally trashes the engine.
Run-on or (Diesel ) is caused by low grade fuel. Also if the timing is set a little too high, meaning you need higher octane this will happen. Have the timing checked, lower it by a few degrees. With the price of high octane, a lower timing in the engine is the best solution. If you continue to have problems, make sure the idle rpm of the engine is not too high, if it is high, reset to factory spec's. If you still have problems, just turn the engine off while still in drive, then put it in park.
You will have to remove the drive belts from the front/ side of engine along with vibration pulley dampener, and accessory drive, then remove timing cover assembly and you will expose the timing belt, ensure that you sent your timing marks and TDC before removing and replacing timing belt, ensure not to rotate engine while timing belt is removed and re assemble in reverse order.
150 yearly acidents happen because people drive while high
It can happen in some vehicles. That's one of the reasons so many manufacturers have a time schedule for replacing the timing belt.
Timing belts last about 70,000 miles. You should change the water pump while you're in there; Honda likes to drive them off the timing belt, they wear out about as fast as the timing belt does, and since you're in there anyway...
Slim, but it has happened to me two times over the last 40 years and I drive a lot;
A bad timing belt could make the engine shut down but it would only happen once, not sometimes.
Your fuel pump should ALWAYS run while you drive, because it's electric and if the fuel pump wasn't running the gas wouldn't move through the car.
Not a good idea. Just think what would happen if it broke while you were driving.
A timing belt is a belt that usually features teeth on the inside surface, while a timing chain is a roller chain. Most modern production automobile engines utilize a timing belt or chain to synchronize crankshaft and camshaft rotation; some engines instead utilize gears to directly drive the camshafts.
