OK my 96 SL500 is acting semi weird. On taking turns, seems mostly to the left, my ASR light goes on and the throttle cuts back like I would expect with wheel slippage, but the wheels are definitely not slipping. This happens at low and high speeds, hard and light cornering. It only happens once in a while though, so its hard to peg down.
I did get new 18" wheels for the car, and the problem seems a bit worse with the new wheels, but the problem was there before the new wheels.
This is a weird and very annoying problem!!
