ADSMAN

Check engine light came on, throttle is vibrating hard and hesitating big time, so I'm guessing coil since I had almost the exact same symptoms in my audi?...hopefully? Any ideas on what it will cost to fix non dealer?

Coils would not be my guess. Best read the error codes before you order coils. I'd not drive the car much if at all too. Not that I necessarily fear the worst but say if it is as I suspect an AOS there's a risk in driving the car.

For cost at an indy you'll have to call around and get quotes. Prices vary from shop to shop and certainly from region to region.
