Kia Troubleshooting Questions? Ask a Mechanic
Hello and welcome! My name is ***** ***** I can assist you with your question. This is caused by an air or a vacuum leak or a bad throttle body. Also, be sure to check the mass air flow sensor and air intake snorkle for any cracks or rips as this can cause the air fuel ratio to be off significantly at idle.
Hello and sorry for the delay! YES, it can be a bad idle air control motor. However, my experience is that if this is bad, it would be an issue all the time. Not just when the AC is on. But yes, to answer your question, it is possible.
