My grandpa gave me his truck which is my new dd. I've been driving it for about 2 weeks now and noticed a few things. It's a 5.0L w/ 69k miles on it and an AOD tranny. Its had been sitting for awile so it needs a little TLC. It has had a new belt and hoses put on it within the last few years, but that is the only work done to it that I know of.

It runs a little rough and sometimes sitting in traffic it'll surge up just once and then go back down to idle rpm. Old gas isn't the problem and I can't find any vacume leaks, everything underhood appears to be ok. The only thing I know is wrong with it, is it has an exhaust leak behind the cab close to one of the cats. No SES/CE light. Any ideas of where to start besides cap, rotor, plugs, wires and fuel filter?

The other thing is the AOE tranny shifts real hard into OD. 1st-2nd-3rd shift fine but OD hits hard. Should I get the tranny flushed or?

Are there any little things I should do to it as in free/cheap mods? This truck is stock as stock can get.

Thanks in advance.

 

Not sure about some of the other issues, but as far as the surging, the older Fords had issues with throttle postion sensors, and the trannys in all my Fords have shifted rough into gears.
