it appears you might have two issues, from those logs
1. maf and or wiring, there seems to be a lot of noise and drop outs
2. the fuel trims with the rpm tests, suggest you have an air leak
i would first check for air leak, as suggest a smoke test
and log again, you should find that long term trims at idle should counter to 1, if the air leak is fixed
as far as maf, you would need a scope to actually check the signal correctly
you can perform a voltage drop test to verify the power and grounds are sound, a poor ground could result in a poor signal
try that and report what you find.
