Car is back from the shop. They did a great job and charged me less than quoted. I highly recommend Ballard Auto to anyone in the Seattle area. The drivers side engine mount was broken and the left was very worn. The car is running perfectly again so I have no idea what was causing the no idle issue. Hopefully it doesn't crop up again, but I will be doing a lot of electrical work on the car this summer coupled with some top end bolt-ons so it will get a going through. Thank you for the help everyone!
