high idle speed fixed
I have a California 1991 420SEL with a check engine light. The X/92 diagnostic connector on the firewall close to the battery has an LED that displays 9 flashes when the button is pushed for 2-4 seconds. I would appreciate a table for the trouble codes on this car.
Your help is appreciated...thanks.
