You did a tune up consisting of what? New spark plugs, cap & rotor (if equipped), new air filter, new pcv? We need more info to really help you out here.

When was the last time you changed the spark plug wires?
Did you also change the fan belts and check for proper tension?

Engine flush is ok, did you do it yourself?
Beware of oil leaks soon. That stuff is pretty harsh on old gaskets in high milage cars. Also you really should just change your oil & filter every 5 to 7000km, skip that engine flush stuff.
