I have an 05 Audi A4. After I come to a complete stop, I now step on the gas and my car sometimes doesn't speed up as quick. It's almost like the car has to think about it for a minute then it speeds up. However, other times it speeds up just fine. The Audi dealership has no answers. Any opinions?

 

Have you tried the basic things like fuel injector cleaner, spark plugs, air filter clogging, etc?

Also, when you step on the gas, do the RPMs go up before it starts to move?

Oh.. and has it always done this? Is it possible that it's just sluggish starting off, but the acceleration that you feel is when the turbo starts spooling up?
