E30=Idle Speed Control Circuit Problem. Some switch is out of adjustment: TPS/Power Steering Sw/park or neutral safety sw. Out of adjustment minimum air rate, ISC/TPS can cause ISC not to control idle. E30 could also be a false code Long diagnostic 'tree' to follow.....

87, ya Dave S Texas is right, sorry. On the top speed, I'd say 120 mph.
