Restricted Engine
Hey guys,
I have an '05 F-150 XLT SCREW 4x4 and for the last year I've been having some trouble with it. It started out that the driver side catalytic converter crapped out and I could hear pieces of the internals of the converter banging around in there. The other symptoms were that when I'd put the pedal full tilt the engine would cut out and feel like it was bogging down or misfiring. The engine light came on and gave a 'catlyst' error. I took it in under warranty and got that cat replaced. Within a week the passenger side cat did the same thing. Took it in under warranty and got it replaced. However, this never really fixed the problem of the engine bogging down and now I'm out of warranty.
The problem I've been having is the same as I did when my cats were crapping out. The difference is I don't hear anything banging around down there at idle. However when I slam on the gas if needed..... sometimes the engine will bog up and I'll have to let off the gas and sometimes I'll hear a loud bang like metal slamming against metal underneath me (driver side) and the engine will open up with no problems. The other day the engine bogged up a little while I was just cruising at about 50mph. I'm concerned that there is a piece of one of my old cat's internals just hanging out in my exhaust pipe between the cat and the muffler causing this issue. I don't get any engine codes except if when the engine starts bogging up I stay on the gas rather than letting off it. When I do that the engine light starts blinking to indicate a misfire.
I don't have any mods on my truck except a K&N FIPK that I put on about 2 weeks ago. The problem was happening way before this install. Also I'm at about 67,000 miles on the truck.
Thanks for any help.
