rpm drop	Sign In

I have a 2001 blazer 4x4 that had begun to have rpm drop when put into drive. Drops to about 200 and stalls. This problem is intermittent . What should I check?

Thanks.

Let me elaborate a little

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and 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.
