I had the same symptoms....varying occurences but the frequency increased
until the vehicle was not drivable. In the end, the vehicle stopping
distances became too long UNLESS I pushed the ABS switch on the dash after
starting the 90Q. I have not resolved the mis-aligned ABS sensor(s) but I
know that it is the ABS.
