A bad cat affecting only one cylinder? I personally find it hard to believe a cat can affect any cylinders. This will open the door for me to get hammered.

ive read 2 or 3 threads about cats making it misfire on 1 or 2 cylinders..... so i guess its possible..
alot of these model trucks are having cat problems...hmm... i beleive the warrenty on them are like 80 or 100k...(i think)

08 F150 LIMITED
truckie86, try this cause you have nothing to lose.
1. Turn key to NO position but don't start, wait for the chimes to stop, then press the gas pedal slowly to the floor and then let it up as fast as you can.
2.Turn key to the OFF position.
3.Do 1. and 2. a total of three times.
4. Start vehicle and see if you need to do anything else to fix.

Son had a similar problem with his 06 F150 5.4.
Dealer claims it's a bad cat converter. Loss of power on hills and unable to tow anything. Cab smells of exhaust and uses fuel like a 1/4 miler. Will let you know if the cat is the fix. byw: his cat is under a 80,000 miler warranty and his still has 2,000 left..
Update:
Cat replacement fixed the issues. He just made a trip to FLA without any issues..

What's the "NO" position?? Just for *****s and giggles I'm going to try this, out of curiosity what's the reasoning behind this?
*edit* just went out and tried this.. we'll see what happens when I'm going down the freeway tomorrow..
