Cadillac Repair: Idle Adjustment for 1993 5.7 L, cadillac fleetwood brougham, 1993 cadillac fleetwood


Question
I have a 1993 Cadillac Fleetwood Brougham with a 5.7 L engine.  The idle is too high.  Can this be adjusted, and if so how?

Thanks in advance

Answer
IS or HAS the CHECK ENGINE light ever illuminated on the dash while driving the car ?.

In most cases the fault is either a vacuum leak or a faulty ISC motor that has to be replaced and adjusted to manufacturers specifications.

If you do not find any vacuum leaks, E-mail: onlineautohelp@msn.com for pictures and directives on replacing the ISC (idle speed control ) motor.
