I have caused a new problem by mistake on my car. Car is 1987 E30 320i. On sunday while replacing my badly worn throttle cable I noticed that the Throttle Position Sensor was out of adjustment. I could bearly hear a faint click when the throttle was about half way through it's normal travel. I decided to clean it out and set it so that it was clicking just as the throttle came to the rest position which the Haynes manual says is perfect. Only problem now is that the idling has rose and stuck at about 1500RPM. I have tested the switch with a mutli meter and there is a closed circuit at the rest position. It does this irrespective of whether the engine is cold or hot. Could the mechanic that services my car every so often have some how adjusted all the cars settings for the incorrect position of the throttle switch and would the switch really throw the idling out that much? I mean with the new postion on the switch, the car has a lot more power when I put my foot down because the switch now makes contact when the throttle is fully open. This has made the car a lot more fun when I put my foot down. Only problem is the idling now.
Any ideas on how to sort out the problem? Before somebody suggests it, the new throttle cable is adjusted ok and does not bind on or hold the throttle. There is about 1.5mm play on it which seems to be ok. Would the best plan just be to dismantle all the throttle again and put it back where I think it was
Thanks
