Re: odd revs and engine buzzing
The only thing that comes to mind is to check out all 4 of your wheel speed sensor wiring harnesses. They will be mounted on a little clip just behind the wheel bearing.
In my experience, sometimes they would fall off the clips and be hanging there.
The ABS system is very sensitive when it comes to the voltage from the wheel speed sensors...its supposed to be...so when they hang, or flop around, or the connections are dirty or corroded, it can sometimes make the ABS engage when its not necessary.
It doesnt always throw a light either, I had some brief issues with this, caused me to nail a parking curb one day, and nearly rear end another car another day. It was both low speed, not hard, braking, but the ABS "fighting" me, wouldnt let the car stop.
I pulled, cleaned, and reconnected all the wiring connections at the wheels, and went so far as to zip-tie the front two harnesses to their mounting clips, because they were the ones always falling off.
Something to try at least.....
