Anything else

Lots of great input! Nobody is wrong but here's what my order would be.
1. Get the motor running smooth. You haven't mentioned (or I missed it) how old the fuel is. If fuel has been in as long as the car has been sitting, it may very well be the majority of the rough running you are experiencing. Clear codes and run the car!
2. AFTER motor is running smoothly, change oil and filter. check other fluid levels.
3. After you've gained some confidence you have a good car (you do!). Tackle brakes, starting with fluid flush. Depending on your wheels, you can use your camera phone and seek how brake pads look. Rotor can be visually examined for a lip.
4. I respectfully disagree with changing the IMS/RMS at this point. Even thought the car came to you at no cost, it doesn't mean its worth trowing thousands into this repair. After the car is sorted AND if you decide to keep it, then consider their replacement.

I know there's lots of other stuff to think about doing, but until the car runs smoothly enough to think about keeping, what's the point?

Dghii,-You pretty much covered my general plan , get stuff done to make it drivable then get it into someone a lot more knowledgeable about these and go from there. Have a good recommendation for someone to look at it.

Also need to get my wife to see if her father can provide any history on it, was a certified car at some dealer out in Phoenix so maybes they have something(?)-big if I know but worth tracking down

Changing all the other fluids ( maybes drain the fuel as well ) and slowly get bits replaced before they go.

Thank you everyone else for thoughts, parts arrive next week and will update later on progress with pictures.
