2.3 drivers: AIC (or IAC) hum at startup? Posted by iveand [Email] ![]() ![]() |
Here I call it IAC. Idle Air Controller. C900 board calls it the AIC. I have been having intermitten starting problems over the past year. I have tried many basic things, including swabbing out this IAC (3 times), and re-oiling the pivots. But everything seems to come back to it "sticking" or something until the engine is warmed up. Idle lopes (or dies) for first 1 or 2 minutes while system warms up. Then it all runs great. After warm, no problems.
My question for 2.3L NA drivers: with the key on, but engine off, do you hear a noticible hum from your IAC when you have the hood up? Make sure to have the interior fan off, as it makes a lot of noise. But could someone verify this noticible hum? I am wondering if the IAC has problems, but I don't want to spend $300 on another one to troubleshoot. Could someone go out and listen on their lunchbreak and get back to me? Thanks a lot.
