What is your question?
car starts and idles but when it hits 1400 rpm up to 2000 rpm it idles rough, anything above 2000 rpm runs fine
How long has your 1999 Audi A4 Quattro had this problem?
two months

Start with having the check engine light diagnosed it should have codes in the computer that are related to your "idle" problem.
