No service light. On the Series III it has drive by wire and some type of auto start, when you turn the key, it isn't as if you are turing the starter, like cranking the motor you turn the key and it more or less turns a switch on to start the motor. Well the motor starts and idles at 400-500 rpms for a few seconds then it gradually revs up to maybe a 1000 but after a few more seconds, it will idle down to 500 again, even cold, and I notice on the back side of the throttle body that there is oil on it, like enough to sip it off with your fingers, and very dirty for haveing only 50K on it. Whats more, it feels like there is a loss of power. I have checked all the coils and the plugs are ok too. there is also no loss of coolant. Maybe a dirty IAC or something, I am unfamiliar with the drive by wire system, or even the series II, my bonnie was the series I.
Hope this helps you help me
