[merchjo]

As I posted in another message, I had a check engine light and code P0300. After bring it to the dealer they said my truck need TSB-09-007-06 to fix the issue (misfire at idle).

Well I got the truck back lastnight and driving it to work this morning I can said the engine is alot smoother at idle and seems to have more power. I will continue to track and and see if my milage changes.

Here is the TSB

This looks like its for 2005-2006 models? And it requires replacing the exhaust manifold gaskets, along with the intake valve and lock valve, as well as the head gasket. Wow that's alot of work.

Thanks for the post. Moving it over to the TSB section so it can be easily found.

Yea took them 2.5 days after they got the parts. The truck was in the shop for a total of 2 weeks.
