When the motor is worm and I step on the brakes the idle drops and comes back in a 2 second rithm. Up and down, up and down as long as my foot is on the brakes. The brakes work fine. I let off brakes it idles fine. I replaced the brake booster and it helped a little bit. It is possable the rebuilt booster is bad. How do I check that? I checked the one way check valve in the vacuum line to booster it seems to be working ok.
