        Hi DB, without the presence of your vehicle we would not be able to properly diagnose it, nor provide you with a 100% answer. I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

    • Q:

      Cutlass Ciera was missing a little bit, so I cleaned the IAC. I put it back in and it runs even worse than before. It runs very rough in gear idling, but runs great at speed or beyond idle. Did I break the IAC or is it just going out? I really don't want to pay 60 dollars for a part I don't need. Could it be something else?

        With reference to your inquiry on the BWD Idle Air Control Valve -part# 21767, the idle air control valve may be the possible cause of the problem on your Cutlass Ciera. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem. For any further assistance, you may also call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.

    • Q:

      While running beautifully, will a faulty part no. 21767/Idle Air Control Valve cause the vehicle to stop completely. Restarts most of the time, but still mighty scary and expensive to tow and while in traffic.

    • Q:

      1991 Buick Century - Will a Faulty IAC cause the idle to speed up after it has reached running temp? I have cleaned the IAC and it functioned great however, 2 days later it started increasing speed after getting to running temp. The orginal issue was the idle speed was way to fast also the ck eng. light came on before the speed increases. Should the IAC be replaced & could this be the problem ?
