Maintenance/Repairs

My 93 previa recently went in for brakes, shocks, and tune up. 320,000 miles original owner. Afterwards it ran rough. The o2 sensor needed replacing. When I got it back it ran rough. Mechanic assured me it just needed a little time. It has the following issues:
Left front would shudder like an out of balance tire between 50-70. Replaced tire.
Now it hesitates and stutters at 70. Feels like its choking out. Won’t climb hills without shifting a lot. No pick up. Gets 12 miles to the gallon instead of 20. First three minutes of driving are okay, after that it rides terrible. I have him looking at it now. He swears it is just because it’s old.
Your thoughts?
