My 1990 325i has a weird problem sometimes when I start it: the recalibrayed will soar up to three grand and then zoom down to 500rpm and fluctuate like that. The check engine light comes on as well. I will then turn the engine off and move my automatic transmission selector slowly through all of the positions and then restart the car. And it will be just fine. So, my question is: what connection is there between the auto gear selector and the idle? What should I be looking at? Thanks . The car has 301,000 miles on it and runs strong with no other idle issues. Rick steady 750 or do at idle. Any ideas?

No connection, unless the TCM thinks the car is in drive. Check the TPS voltage. Try cleaning out the idle speed motor with carb cleaner
