So I just barely failed emissions In WA state on a car with cams and new magnaflow 3in cat. My CO levels are great and HC at cruise is also great, but I fail the idle portion 295 Hc at the limit of 220. The car is idling at 950 and noticed LTFT LO was a little high but was better the night before. Its so close to passing, do you guys think just the MAF needs calibrated a little more? Another thing I noticed, the cat has a burning smell. Could this also be throwing off my idle HC?
