I have no answer but an interesting story...
Unplugged MAF leaving work headed to the gym at lunch (at 21000ish miles)..drove ~10 miles...CEL came on...knew it was going to happen, but could not stand it being on. Plugged MAF in after the 10 mile trip. CEL cleared after 3 or so starts. Same week, with MAF still plugged back in, CEL started comming on and off after a few start cycles...I was confused, part store scanner said insufficeint EGR flow and low turbo boost...dealer replaced EGR that week, no CEL since (~1000K) and have not unplugged the MAF either. I assume unplugging the MAF and the EGR going bad are mutually exclusive, but I really do not like the little orange light on the dash

and am scared to unplugg the darn thing...
I get 20.5-21 in town and about 26 OTR...but naturally wish I could get what the motor is capable of...
