[QUOTE="Rix, post: 1346930, member: 17306"] check your fresh air ports on the o2 sensor, clean the MAF sensor with non clorinated brake clean, that's about it. If something with the o2 sensor was wrong that was going to show on a DMM, you'd probably see a code for it. The sensor can be sluggish and cause lean, but still be within "normal" parameters, but you have to watch fuel trims or o2 sensor voltages (VF and ox or ox1 in the diag box) to tell that. Could also have injectors starting to spray poorly. As for aftermarket MAF sensors.... I can't recommenda good one beside OEM. [/QUOTE]
