1997 OBS "Driving" Issue

[Animal25RS]

Recently bought a '97 OBS, has minor problems. Main problem that i've found and can't figure out what it is:

I start out from my garage, 1st-2nd-3rd-4th...all fine (always shifting at 2500rpms), get 2miles out onto higher mph roads, 1st-2nd-3rd all fine, but as i try to shift into 4th (there's a lag of power an my speed is dropping as my foot is on the gas, i have to really "STEP ON IT" to make it gain the power back and go!). 5th gear is the same way after i shift out of 4th (the lag process starts all over again)! Now that I'm approx 4miles away from my house, that lag process is happening to ALL THE GEARS. A buddy says its the alternator (its bad), true?

Please help!? Any and all help is greatly appreciated

Thank you.

Well, its easy enough to have the electrical system tested. Every shop I've been in has always advertised it being a free check.

is there a check engine light?

if so, then have the codes read at an auto parts place.

Advanced auto or Autozone will read the codes for free, and like stein said, they can also test the alternators

are your headlights getting dim while driving? if so, then it's the alternator. is the car shaking? maybe bad engine grounds

or stuck throttle?

Found out that its the alternator.

Need some help from other '97 2.2 owners or subaru Guru's or people "in the know", I'm looking for a wiring schematic of the engine harness and i can't seem to find anything, i could use all the help i can get, please?

Specifically what part of the wiring.

Alternator wiring in engine bay and under the dashboard.
