Rough Idle at Start Up - Recall Repair 0012MC
My dealer did the recall repair for 0012MC which calls for replacing tensioners and low intake manifold gasket. This fixed the problem (the rough idle was caused by a leaking gasket...the tensioner was a side item to replaced under the same recall).
Was getting a lean engine code and after replacing the O2 sensors it still didn't fix it The recall is over now, but replacing the lower intake gasket fixed this problem for me.
