Thanks Steve, no check engine light has come on, sorry for the mix
up but it is a 2012. I would assume their would be no codes?<br>

<div dir="ltr">According to Nada Guides, there was a 4.6 V8 and
a 5.4 V8 in model year 2010, and in model year 2011 they
changed to a 3.7 V6 and a 5.0 V8. Sorry but I don't have a
lot of input on the problem. Clogged catalytic converter is
definitely on the list based on the symptoms. Fuel filter is
another guess. Apparently there's no Check Engine lamp? I am
still trying to think how oil pressure could play a role. It
shouldn't be able to get high, as there's always a relief
valve in there somewhere. What if that failed... what would
high oil pressure do? Well, really really stretching here but
if there's any variable valve timing arrangement on that
engine, they sometimes actuate it with oil pressure...</div>

Thought the 5.0 was long gone before 2010. <br>
Think my son's 2002 is a 4.6?<br>
