sounds to me like when you cut the wires for the MAF the connections weren't on tightly enough and now that you've got the afc pulled out, the wires are still not tightly connected still. I personally soldered all my connections and gave it a shot that way. Also I had a bit of a problem with the white plug further up on the engine harness getting loose without my noticing but about half an hour later, I found it. Give those a shot and see what's up.

I agree on the white plug issue...For some reason they just come un-done!

As for your connections, go through anywhere you have made a connection and solder it. Do not use the crimps/butt connectors on the wires as they simply come loose too easily.
