Code 16891

[dzanan]

Drove the car for an hour commute out of town and installed a short shifter with a friend and drove it back the next day. Me and the girlfriend decided to get food and im on my way home and all of a sudden i had to stop ahead and i put it into first and shift into second and all of a sudden i cannot push the gas or when i can its just surging. Im not in limp mode but the cars idle is just EVERYWHERE. I had to push the car a couple blocks back into my garage and i turned it back on and the smell of gas is so strong. Ive never seen anything like this before. I have the codes

16891
17861 (i knew about this one previously)
17865 (also knew about this one previously)

Ive been slowing fixing every CEL light i can before i start putting go fast mods in like any sane human being should. Im looking for advice about what im looking to start throwing money at now cause i know thats whats gunna have to happen If anyone has any ideas please suggest them. Discuss. Debate. Yell at me for buying an audi. I have done a search on the forums but the possibilities are all over the place. If a video will help of whats going on i can post one as well. Although i may cry because of the noises its making

Thanks in advance guys!
