If it ain't broke then don't fix it. The proper way to test your MAF sensor and the other sensors is to run a full function odb-ii scanner. The read out with this type scan tool is in grams/sec. The reason why driveability with it disconnected is not affected with the exception of the flaky idle is the PCM module sees the lack of MAF input and uses pre-programmed parameters and other sensors like TPS and MAP, etc. However, if your MAF is flaky disconnecting it a good idea for troubleshooting purposes.
