If it were mine, I would go through it thoroughly before I would drive it too hard:
Fresh plugs, gapped right
check the wires for resistance and replace as necessary.
Get the trans serviced
Rear Diff fluid (swap in synthetic)
Clean or replace air filter
Make sure serpentine belt is properly tightened
Check vacuum lines for cracking
Check brake pads/rotors
Check fuel pressure at idle and at W.O.T.
