2005 LE 4X4 with 49,000 miles.
I have noticed within the last few days power loss, mostly at WOT. If you turn on the AC the truck cant get out of it's own way. It lumbers along taking forever to gain speed refusing to down shift.

Last year I had both exhaust manifolds replaced. Other then that its been a good truck. Anyone have any ideas???

From reading the forums, I'm thinking the Cat. converters??? However, the new manifolds had new ones??? Maybe the ones behind those???

If it is the Cats does anyone know if they are covered under the emissions warranty??

Thanks guys. I really do appreicate your help.

Molt likely causes are bad fuel pump or converters.

ok I'm taking it in on Monday I'll have them check it.

Thx!!
