Manifold Exhaust replacement?
 

The weather just got cold so my engine has been shivering a little upon startup. However, just a couple days ago, I started it up and it start shuddering pretty hard. Then the CEL light went on. I brought into the dealer and he told me it's probably the manifold exhaust and they're going to replace it. He said some others have brought it in for the same reason, and it's like a "recall".

How come I haven't heard anythin about this on the forum? Anybody else?
