When you say fishtailing, does it feel like the back or front is shifting back and forth. If the back, check track bars, axle shifting on springs, worn bushings. If the front, check for the normal loose stuff and also check to see if caster shims are missing. if the caster is not positive enough or too much, it will be squirrely
As for the losing power, the cam sensors are notoriously causing trouble.

Wow! Thanks for the drawings. I am a picture kind of person. All things things don't seem that "bad" of an issue to fix. I can't tell if I have it fixed until I drive it a couple of hundred miles. So I am going to clean everything and make sure the gas cap vent is working.

The fishtailing- I have had someone drive behind and they say they see the whole bus move. The Tires are new Goodyear G661. The psi was 115 and I lowered it to 105 and that did not seem to do anything. Maybe down to 95? I have a feeling the fishtailing is connected to the air ride. The air ride was not original equipment on this bus I have been told it was added later. And I will have the caster checked as a mechanic told me if the caster is off that will make it not steer correctly. Even though I had it aligned when the new tires were put on.

Again thank you so much!

I have made notes. Printed out the picture and photo. And I am off the visit with a recommended mechanic. They fix semi's, RV's and are a Ford powerstroke expert. They should be able to do everything except check the caster on the alignment. And that shop is a few blocks away from them.

Thanks!

Where are you in FL? I know of one shop around Davenport but I haven't checked them out.

I am in Pinellas Park. Near St. Pete-Clearwater area. Davenport is a couple of hours drive from me.

Have someone competent check the rear axle setup. If whoever did your alignment is honest, they would have checked/corrected any caster issue. Caster will cause the front end to be unstable and the steering wheel not to return straight after a turn, but it won't cause the rear end to fishtail. That has to be in the rear suspension.

I'd set the bag heights/pressures back to normal, and then check all of the bushings in the rear suspension for looseness. Something back there is amiss.

Try a simple free check. Measure your wheelbase side to side.

I just swapped the fuel tank on my Excursion today. Here are some pics of what I found inside. Definitely check your filters and screens.

You don't need a new tank. I just go one to speed up the swap and mods I made to the tank. I wanted you see what was in the screens. I got mine from craigslist for $100. New about $2500.
