TOYOTA COROLLA ENGINE PROBLEM

1986 Toyota Corolla

Sometimes when braking the engine will stall. Also when cold started, sometimes it will not hold the idle and the engine will stall. Also, when you are sitting at an idle, the vehicle will shake radically. What is the possible cause of these issues.

First eliminate all vacuum or air leaks in the system. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
