The car misfire during acceleration only and then the check engine light blinks

Check fuel injectors and ignition coil

I am betting coil pack. They are currently under nationwide recall.

agreed, my old dealer said they inspected it, and said no replacement necessary. I brought it to another nearby Audi dealer for other reasons, and they replaced them at no charge and I didn't even request it. Also MIL hasn't come back.

Thanks for the replay.
Last week audi dealer replaced all 6 ignition coils.
Still the same problem- misfire cylinder 1 and 3.
How do I check the fuel injectors?

IMD

Yup...which reminds me that it's time to replace mine.

curious....how many miles you have on your 3.2?..
(here in sweden there have been almost every 3.2 2005 year model with cam chain tensioner failures costing a lot of money to get fixed... )

Almost certainly an issue with carbon deposits in your engine valves. I had the same problem with mine. At first they replaced my spark plugs and coil packs, but the misfires kept occurring...then they finally cleaned my engine valves and I haven't had a CEL since. It's been about a year since the valves were cleaned.
