stutter, lack of power 90 legacy wagon AT, AWD

have a 1990 legacy with 220,000 miles. small hole in exhaust. has stuttering, random dead spots when trying to accelerate.

seems to be when cold? and when it does makes mileage go poor.

any ideas? i checked resistence on coil pack and fuel injectors becuase suspected ignition problem?

pcv stuck, but was changed about 10000 ago?

too many things to check? MAF sensor? o2 sensor? where to start.

oh, when i take out the plugs they look okay. thanks!
