sounds similar to misfire while driving hard?

[engineerjet]

I have APR K04 on my A4 and i have all new spark plugs (recommended brand and gap according to APR's site) and coils. During hard driving usually in second and third gear, when i floor it the car seems to struggle and i feel a slight shake that i can only describe as similar to a misfire. No misfire codes are thrown though. Occasionally I would get the code P2014 and P0089 (the P2014 code may pop either during driving or after i turn the car off and pop up the next time i start the car) but I'm not sure if they are relevant. I replaced my flap motor a while back and still need to get it adapted (could a non adapted flap motor be the culprit?). Has anyone else had issues like this?

are your Ignition coils new you said? what are your plugs gapped too? and what type of plugs? remember you are suppose to run colder plugs.

The P0089 code could be caused by the lpfp control module. I ed a RS4 lpfp control module and it fixed the wot fuel cuts that made it like its was misfiring. To confirm this run some data logs and
Feel free to PM as we have the same set up basically

Hows your fueling?

I would agree with a fueling issue.
