Re: emissions leak
Do you hear a ticking noise when your truck is running. I had the same problem with my truck last week. I took it in and it turned out that my exhaust manifolds were cracked. They have have an extended emissions warranty of 8yrs / 80,000 miles. I would just take it to the dealership and have them check it out if you are still under the warranty, or you can just start and one end of the exhaust while the truck is running, and put your hand about an inch from the tubing and see if you feel air do this for the entire exhaust.
