brake light vacuum problem?

[Tyrret]

My brake light comes on then the rear anti lock brake light comes on when i pull away from a stop sign all go off and stay off until I let off the gas then once in awhile the brake light will come on again and the arbs less often sometimes not at all also engine seems to lope alittle at idle but fine at all other speeds more pronounced when cold gas mileage has taken a bit of a hit also. any ideas possibly a vacuum problem?

i think it could be your IAC valve or a mix of IAC and vacuum. the ABS im guessing is just the sensors are trippin. perhaps they are diry.

Have you checked your brake fluid? Heavy acceleration or braking can cause the fluid to roll around in the reservoir, and trip the fluid level sensor.
