Apparently never! I can't find it in my records. Weird. So 106,000 km and 6 yrs! Buying one tomorrow. The MAFS is/was clean as a whistle but I cleaned it anyway.
Maybe your gas mileage will increase as a result. Was the filter very dirty?
Yeah, who knows. I just can't believe I never bought a filter for it. Fusion and truck get one every year...this thing...guess it was a lot of WhoTFCs.
It wasn't horribly dirty, barely got any dust out of it, but still...6 yrs is a long time.
Friend who works at Piston Ring contacted his friend who works across the street (GM guru) - said unplug it and drive it. If it doesn't do whatever it was doing, it's the MAF. So this AM I unplugged it and drove to work...and sure enough, no sputter lugging from low in 2nd past 2000 RPM. Just pulled and off she went. Racecar! No heat though. Full boil and was only keeping it comfy in the cabin. Not burn your face off like normal. So I guess I won't be not replacing the MAF. Guess there's more connected to it than just reading the air.
So, I called the GM dealer...$110.75 for the MAF, and $45 (WTF!?!?!!
) for an air filter. C'mon! WIX is $56 he says. About $175 all in. Or you could cheap out on a POS he wouldn't use to filter gravel in his wheelbarrow for about $19. Yeah, no. Agree there.
Checked with my friend at PR...he can't match...he's even higher. Another WTF. He says check Rock Auto. So that's where I'm getting both from. $88 CDN for both a new air filter and MAF, including shipping. $2 at the shipping place...and whatever the guys at Customs want to hit me with (hopefully someone I know on duty
) Should be here next week. Won't have the car here anyway, so suits me fine.
