Well, I put a new voltage regulator on, and that seemed to have cured the issue. 1K miles with no ABS light.

Today was another story. The ABS light is now coming on for extended periods of time (at least 5 minutes sometimes more).

While the ABS light is on, my idle gets VERY poor, hovering around 450 when in drive, and almost stalling. In park or neutral it climbs back up to 700 but still idles roughly.

I managed to get my meter on it while it was doing this behavior and I found my system voltage to be 13.5 at idle, in neutral.

As soon as the light goes out, my idle returns to normal and my engine power comes back.

Any ideas???
