intermittant problem, stays for months goes away for weeks.Abs and check
engine comes light on.
When working rear calipers and pressure seem fine.
Thought it was one of the two solenoids on the abs
valve(sticking)but after looking at valve, each solenoid has a front and
rear brake line going to it and the front brakes work fine.
Any idea's on where to start.......thx

If you scan the abs with an abs function scanner may be able to pin down the
source of the problem.

Have you taken the black plastic cover off of the bottom of the
hydraulic modulator?
One of the gears inside may have come loose.
Be careful, don't lose the gear and screw.
