car idles too fast after the dealer replaced the throttle position sensor and idle speed actuator
The car was idling extremely fast so we took it to a caddy dealer and they replaced the throttle sensor and idle speed actuator. I helped but still idles too fast especially after warm up. seems to be progressingly getting worse. any ideas?
Maybe get the idle air control valve looked at. My car had a high and fast idle. A couple friends of mine figured it out and thats what we came out with. We switched the valve and that solved a lot of problems. Try it, it may work.
