Hey guys, so my wife tells me sometimes when driving the expedition it feels like the brakes are engaging and disengaging randomly (She drove it all around town like that 
) She's not great at giving specifics, and, as usual, when I drove it, it drove perfectly fine. The check engine light was on, so I pulled the codes and found one for bank 2 sensor 1 O2S and one for random misfire, and that was it (don't recall the specific codes). I knew about the O2S and the misfire was related to a bad IAC solenoid, so I replaced both and changed the oil while I was at it. Still no issues when I drive it. The ABS light was on when I first scanned the CEL, but I don't have a way to scan ABS. When we first got it, it had the infamous w/s leak and shorted GEM module. We replaced both, but I seem to recall the brakes doing something similar before that, but there were other electrical gremlins, and the floor was wet. This time, only the brakes are acting up, and the floor is dry. Is there anything that can cause that to happen that I'm missing?
BTW this is a 2001 with 5.4 and 2wd.
