2011 eco 1.4 turbo automatic

Got an engine chirping sound at idle up to 900rpm. It goes away anywhere above 900rpm.
Hard to tell where its coming from . Shot some degreaser on the belt, no change.
Any suggestions

I would check the spark plugs. I had this happen once, and retorquing the spark plugs resolved the issue. If they are under torqued it can cause a chirping noise as air squeaks out.

Could not wait till tomorrow. Removed the plugs-none seemed loose. One plug was tight coming out and may have been the culprit. Check the gap at .028. Reset the plugs at 216 inch/lbs.
Noise, that was always there, is GONE!
If you visit NY at any time ,look me up, drinks are on me!

Thanks for your concern and response. If you read thread #9 you will see I solved the problem thanks to member dhpnet's response. A simple plug spark pull and retorqueing solved the problem. Probably saved $1000 vs. the cost of going to a dealership.

Reading the threads of today I had to listen to that video. Simply amazing how a spark plug could make that noise! Very weird, I' glad someone posted the video of the noise, as that is not the traditional chirping I was thinking about.

Amazing-

Glad you found that one, that could have been a ton of parts and time and still a squeak.

What an excellent forum this is. It was this thread that helped me find and fix the chirping noise that developed recently. I was fiquring a trip to the dealer and how many dollars this was going to be. But after finding this thread and 1/2 hour in the driveway, gapping and retorquing the plugs, squeak is GONE! Number 2 plug was loose and sooty, 2 others were loose but not finger loose. All fixed and running great again. Thanks to this group and the videos that were posted also.

Thanks for the thread and the video! I've been chasing this for 2 weeks on my Cruze, put a new belt tensioner on, and was getting ready to do the water pump because I thought that may have been it. I hate throwing parts at cars without a proper diagnosis.

My car was making the same exact noise. I popped the coil pack out, sure enough, number 3 was loose and 4 wasn't all that tight.

Thanks again for helping me out big time!
