*Solved* CEL PO100/$07E8 Mass or Volume Air Flow A Circuit Code Diagnosis *Solved*

Hi! Recently the car started jerking periodically. I removed the MAF and did the CRC MAF cleaner and ziplock bag trick and watched all the dirt come out of the MAF. I put it back in and the car has been running great for the past two weeks. So what's the issue? The CEL doesn't want to clear. As soon as I clear the code it comes right back. I'm not sure what the problem is since the car seems two be running great.

Anyone got any ideas on what to do next to clear the CEL or fix whatever else is preventing it from clearing?

Thanks for any help!!:headbang:

So - following the lead above, I opened up the wiring from the MAF and started working backwards. About 12" back from the MAF, near the 90 degree bend the blue wire completely snapped as seen in pictures. I checked all the other wires for breaks and didn't see any one. Stripped, soldered and put back. CEL light gone. See pictures for more details.
