Replace the HT leads to the spark plugs.
A timing chain, that needs to be replaced, can cause your engine to run rough and lose power. A broken timing chain can cause significant engine damage.
You do not have the correct timing set for that car.

If the timing chain has jumped time, the vehicle will run rough or not at all. You will need to check the time with a timing light to see if it is off.
If the engine runs rough after a timing belt change, the belt may not have been tightened properly. It may also mean that the wrong timing belt was installed. Either way, it needs to be taken back to the mechanic.
replace timing chain
timing off
Not unless the bearing in that pulley is noisy or rough when you spin it.
Your timing is off. Buy a timing light.
