Hello everyone,
I have a little problem (or at least I hope its little). Sometimes when my car idles the RPMs jump up and down. I have no idea why it would do it.

Can someone please tell me what is causing it and how do I fix it?
Thanks

Change out your O2 sensors, clean your MAF, and double check the harnesses for cracking or wear on both.
