If this is a long term buy get the manual. The EFI settings will need checking (throttle position etc) and the air flow resistor may need cleaning, O2 sensor change and the throttle by-pass unit cleaned and checked. I would not use 'flushing agents' just service at half the standard period. An injector clean (removed in a test rig type clean) may be a good idea.
