Hello, my 98 deville is acting up a bit.

prob 1: while in Drive and fully stopped there is a rough idle, goes from 625 to 650 to 700 for a fraction of a sec then down to 625 again.

prob 2: while idling the all the lights are gently dimming, keeps going from full brightness to a bit lower then back to full brightness constantly

this is the only code that comes up through the diagnostic, IPCB1910: GENERATOR L-TERMINAL OPEN CIRCUIT PROBLEM

can anyone please help, and what is this generator l-terminal thing?
