Ruined my MAF!
In a quest to try to improve my gas mileage, I had the bright idea of cleaning my 08 LS3 MAF. So I unhooked the battery, carefully removed the MAF, gave 2 quick sprays with CRC MAF cleaner, let it dry for 15 minutes, put the MAF back in, reconnected the battery, and started the car.
It fired up quickly, but then promptly started to sound like a Model T, sputtering until it finally found a somewhat decent idle. I let it run for about 10 minutes, shut it off, started it up again, and got an immediate CEL. Code showed P0102 (MAF low input).
I disconnected the battery again, waited about an hour, fired it up again, and it seemed to start and idle well, and let it idle for 15 minutes. Then turned it off and on again, and the CEL popped back on.
I'm kicking myself because although I run an oiled K&N filter, the MAF didn't even look dirty in the first place. I now have a new one on the way.
When I reinstall it, do I need to have it done by the dealer so they can use a scantool to get rid of the code, or can I just disconnect the battery for 15 minutes, reinstall the MAF and reconnect the battery to clear the code?

Did you touch/wipe the critical areas of the maf (not good) or just spray it with cleaner? If you just sprayed it then I would look for a leak or problem at the connection/wiring before I purchased another.

I just cleaned mine a week ago. sprayed the hell out of it in all directions. then wiped the walls down. i didnt wipe anything but the walls. i let it sit for 10 minutes then installed it.
no issues.
I would get one from a junk yard or car-parts.com before i get a new one

How about I re-installed the MAF upside down? I put it back in the right way and the issue is resolved. Just goes to show you shouldn't work on your car when sleep deprived.

^^ I have proven that with enough determination (and beer) the impossibly simple can be unachievable! Square peg in a round hole is nothing!
Never underestimate the power of determination and in the OP's case, lack of sleep!
