hello I have a 2010 audi s5 it was given to me as a gift and now im playing catch up on what was wrong with it when idling it has a semi-rough idle and when at wot it Boggs hard until about 4-6k rpm then it pulls smooth it doesn't have o2 sensors in but should that be a problem? any idea on how to test the fuel pressure regulator ?
