Engine problems?? (Check engine lights come on)
OK, every morning when I start my car (2000 A8L 4.2L - parked outside under a car port), it runs rough for about a minute and won't accept input from the throttle. It will go from 1200 to 2000 RPM and then drop down again, even tough I keep depressing the accelerator (in neutral). If I put the car into gear, it will "jump" a little like a rodeo horse and again won't accept any throttle input. If put into gear, the car will throw a "Check engine" light as well.
I live in Austin, TX and the car has been doing this throughout the summer (80's and 90's in the morning) as well as now, when we had 50's and 60's in the morining.
I almost always fill up with the highest octane Chevron gas, sometimes Exxon as well. Always the good, expensive stuff. Car had an oil change recently (about 1,500 miles ago) and usually only does city driving, with some longer trips that will sometimes occur on weekends.
After a minute, it runs fine and doesn't give me any more trouble. Some guy at the Audi dealership claims it's a moisture problem, but why does it occur every day?
The "Check engine" light will go off after I have let the car sit for a while and then use it again, usually after 3 or 4 times.
Any ideas what this could be? It annoys the heck out of me and I would like to take care of that and get rid of this effect.
Any suggestions would be appreciated.

Re: Engine problems?? (Check engine lights come on)
you have to pull the codes. I had a similar problem this summer. It turned out to be a bad ignition coil pack. Without the Vag-com, I would have never been able to fix it myself.
