p300,301,303 and misfire
 

I am getting check engine light with message p0300,p0301, and p0303. If I shift under 2500 rpm it drives fine. As I accelerate after that rpm range it sputters and the CEL flashes. When I easy off the throttle ir disappears. When I check with my scan tool those codes pop up. My car is a 2000 A4 1.8t front wheel drive with the ATW engine. Ionly have a K and N drop in and Apr Chip. I changed the plugs with Beru Ultra x plugs 27,179 miles ago. I will include a part from my repair doc.
