All my lights are flickering

I have a '98 GS-T and all my lights flicker while under accelleration. Dash lights, headlights, taillights, everthing. Any help?

Weird dash light activity is the classic symptom of an alternator taking one for the team. Can't say I've ever seen it happen only during acceleration, but it wouldn't surprise me.

Yes, have the alternator checked. If its fine look at the wiring in the fuse box, make sure none of the wires are shorting out.
