Can a bad timing chain cause rough idle?
Can a bad timing chain cause rough idle?
Rough Idle When a timing chain is worn, it develops slack and becomes loose. When this happens, the engine’s valves, which are powered indirectly by the timing chain, will no longer run correctly. When the valves begin to run off-sync, the engine will function poorly and cause the vehicle to have a rough idle.
What causes timing chain problems on Ford 4.6?

What should I do if my timing was not set correctly?

How many timing belts does a car have?
I believe you have two timing belts, one for each head, but even if they have figured out how to use a single belt on a horizontally opposed engine, there are still two (or 4) cams to time and it only takes one to be off a notch to cause a rough idle.

Why does my timing belt keep going off?
If you engine is a VVT (variable valve timing) engine, then it is even easier to get the timing off a notch. But there is one other possibility. If you have balance shafts, one of them could be off time.
