Sounds like two problems, bad idle and no power under 3k rpm.

For the sputtering and no power under 3k:

Could be the plugs, rotor, and cap. Replace them (use only OEM BOSCH)
If you still have problems replace the injector O-rings
Worst case is clogged injectors (the car will run real hot,
and backfire sometimes)  Check the spray pattern and replace
the bad with NEW ones.


Befor spending any money check all the vacuum lines and the intake
boot for cracks.  This is all I can think of at the moment.
