Idle slow and some times cuts off. Like come to stop sign and brake or turn corner. Checked for codes with meter none shows up. Another problem has started the brake and anti lock lights come on after driving. Distance varys before comes on.

Try cleaning out ht ethrottle bore with carb cleaner and arag, this should help stabilize the idle. If your Sub has a throttle cable, clean the Idle Speed Control motor as well. It has 2 Torx screws holding it to the throttle body, with a flat connector. The ABS/Brake lights , check fluid level first in master cyl. If all is ok then you will need to have the system scanned for codes to see what failures the PCM has recorded
