Engine Mechanical problem
1991 Infiniti Q45 V8 Two Wheel Drive Automatic 110000 miles

I have a problem with the rpm's on the vehicle.
I was just driving on the road and the antilock light
came on. When the light came on the engine rpm's
increased from 2000 to 3000. I pulled over and turned the ignition off. The light reset itself and the
vehicle seem to work ok. After driving for a few minutes it happened again. The antilock light came on
and again the rpm's went from 2000 at 60 mph to
3000 rpm's at 60 mph. When I slowed down the
rpm's dropped to about 1000 but the engine was
acting weird, the rpm's would jump up and down and
the vehicle seem to want to shift to another gear.
The car seem like it did not know what rpm it should
be turning at. Can you help with this problem?

Do you
have the same problem?
