8 acting weird...
Earlier today I drove my 8 and everything was fine... but just about an hour ago I turned it on and I immediately noticed something was wrong. The CEL was flashing. It turned over fine but the engine sounded completely different, definitely not as smooth, and every time I tried to move the car I had to give it more gas to keep it from dying. Once I got out of my driveway and tried to go forward I noticed I had quite a bit of power loss.
It was inside a warm garage earlier today for a short period of time and I'm hoping some water melted in it then refroze in a bad place when it sat out in the 12 degree temp for awhile.
My dealership wants 100 bucks just to diagnose the problem...
Does this sound familiar to anyone? After I noticed I had power loss I put it right back in my driveway and turned it off. I'm really worried I'm gonna have quite a large repair bill....

flashing CEL is usually an indication of a misfire.
you coils could be gone, you could have a loose spark plug wire (these do come loose from time to time) or your plugs could be bad.
how old are those 3 items?
done any work on your car lately?
do you have a code reader or know anyone who does? (maybe there's a pending code)

My advice, do it yourself. No experience needed. Just follow the DIY instructions and pics. It will cost you about $30 per coil and $20 per spark plug. You will need 4 of each, so you are looking at about $200. If the dealer does it for you, you can easily double, if not triple that cost.

To have them replaced is expensive 500-600?.
To replace them yourself ~200 bucks. - $80 shipped for the plugs ~$130 for the coils.
For your first time you should definitely be able to knock it out in an afternoon.

I've kept up with all the maintenance myself they just b*tch because I have to change the tires every winter... Literally that's it. They want me to have boring utilitarian car. If I had to get rid of my 8 I would probably cry.
One more thing... When I started my car it seemed to smell a little funny. Are you guys pretty sure its just coils/plugs?

Do you have a stock cat installed? Maybe it's a clogged cat. Just a thought.
Still a good idea to do plugs and coils and wires if it has not been done in a while though.
