anyone who can help
i just bought a 2002 F350, with a 5.4 triton in it, it has 46000 miles, and when i test drove it, it was very nice...... thats almost always wrong with used dealerships......so anyway, it seems to lag a bit, it hesitates to down shift when you are going up a hill ( unless you floor it ) if you give it steady gas when there is a load and you need to accelerate from already moving, it shakes a bit.... the dealership says it just needs tranny service, it will fix everything... my friend at a local mavis tire center, said that it seems to be maybe a clogged cat, because the truck seems to have a rough idle even when sitting still in park, but the RPMs arent jumping up and down...... any other opinions?
also, someone told me in ny ( you might not be from here, but whatever ) cats are warrantied for 8 years? which i guess would mean Ford would have to give them one for free to put on my truck....no?
thanks in advance everyone

Since you bought your truck "pre-owned" and don't have a reliable history, it would be in your best interest to do some basic maintenance. Check the air filter, change the fuel filter, MAF sensor...that sort of thing. Also, without question, an oil and filter change. I would recommend pulling one of the spark plugs to see how it looks. Then take a second feel at how she is running.
Going up a hill: if you leave the throttle at a steady spot, it WILL lag up that hill. Throttle position is what determines how a system will react by giving more fuel and the tranny will respond accordingly to the speed change. By climbing, you are now trying to move 3 tons of weight up a hill instead of across a flat run of asphalt. It will need more juice to get that done. Give it more gas and it will climb.
I am in New York too. Give me a holler anytime. Good Luck!

Nick, WELCOME to FTE!!!
If you don't know the exact history of the vehicle, down to every service, do the following, as far as money and time allows:
Change the fuel filter.
Do the spark plug maintenance. This means remove, clean (or replace), anti-sieze, reinstall, and use dialelectric grease. Replace the COP boots if they are dry rotted or even just "funky"
Clean the MAF.
The "shakes a bit" sounds like you have a low-RPM/high-load miss. That could be a COP. Do the above, and see if it still shakes at that point. If it does, get the misfire counters read, and if there is a specific cylinder misfiring, it might be time for a new COP.
Report back!
