My car's a 1989 929 (US) 18V motor.
The idle on the car is staying at about 1200 RPM after the engine is fully warmed up. The idle has been erratic on the car for a while. Swapping the BAC/ISC with another one didn't seem to make any difference. 132,000 miles, no burning oil problems and runs strong. What should I check to see what might cause this high-idle condition?
