1993 G300 ABS light on= very low idle.
ABS light on dash used to come on intermittently, when its on the idle drops really low and we can smell unburnt petrol in the exhaust.
Now the ABS light is on all the time and it always runs rough.
Its not just a low idle as I turned it up but then when the ABS light turns off it idles really high.
Im sure its something simple
