not sure how picky they are, the long term fuel trims are a little high normally they should stay in the -10 to 10 range, closer to 0 the better. I'm not too familiar with emissions testing areas. Let it idle at operating temp and see what the short term fuel trims do, if they are high at idle you need to be looking for a vacuum leak.
