I just unplugged my MAF sensor while it was running and it stayed on does that mean the MAF is bad or does it just need to be cleaned?

What makes you think the vehicle should stop?

With no MAF sensor it reverts back to open loop and modulates fuel directly based on the primary 02 sensors. Eventually it will throw a code but everything works as it should be.

All this is in the FSM under engine control system if you care to read about it.
