5.4 L lost power
Hey Guys,
My truck has lost power in the past day or so.It will not go over 60 or 3000 rpm. I was trying to merge onto the interstate and couldn't get upto speed.It feels like what I would image a plugged exhaust would feel like.There are no service engine lights on.What should I check first?

My 1995 F-150 did that. Over about 3000 RPM it would just lay down and go slower the more throttle I gave it. It was a clogged catalytic converter. To check it, disconnect your exhaust at the Y pipe and go for a ride. You'll know right away if you fixed the issue.

Thanks for the input guys. The truck is a 2004. I replaced the fuel filter and air filters, They were due anyway. Didnt fix the problem. I tried to loosen the exhaust bolts , But they are rusted on. Sprayed them with PB Blaster and waiting on it to work . RICK.
