If I am stopped at a light and than press the accelerator, the car accelerates, but the shift to the next gear seems late and jerks the car. This might be related to a recent engine light that would come on with the P0012 code. I noticed that the code appears when I am at idle, and the engines idle drops slightly, than the engine light would go on. The light would go off on its own after a day or two.

I have a 2009 non-turbo.
