Hey guys as you know I got an audi here's my info and details on my issue

Year:1996
Make:Audi
Model:A4
Engine:2.8
Trans:5speed manual

Issue:was at a red light getting ready to go put it in first drove off and my whole car feels loose and like the engine is bouncing around. I quickly realized this only happened under/around 2k rpms.

Driving it to work I draw the CEL(check engine light) and I tookittoa near by autozone where I had it scanned misfire cylinder 6 I'm told its a spark plug replace it and no go. Still startes up and drives just feels shitty and jumpy not sure what it is lookin for any input since its my daily driver.this car is completely stock.

Thnx and if you need any more info just post ill do mybestto explain thnx
Pat.
