So far so good. We got it back on 4/29, and as of today we have not experienced any of the problems that started this thread (shudder/shake in idle with a/c on). I am still waiting for the weather to get warmer (it dropped to the 60s as soon as we got it back, and it's still only in the low 70s) to see if it will occur again before I give it a clean bill of health. I did sit in it for 15 minutes yesterday with the a/c on in idle to see if it would do it, but there was no problem at all.

However, on two separate occasions we've experienced a single 'knock' sound when moving forward in drive. Kind of sounds like something shifted under the hood. We looked around under there to see if something was left off, like a cap or something, but didn't see anything. It has only done this twice, and I am wondering if it could be something with the brakes, maybe moving from brake to gas? Something else to keep an eye on, lol!
