Is your "check engine" light on also? The VSC system is automatically turned off whenever the check engine light is on.

This happened to me before my alternator went out.you go can go to a local auto parts store and have them check your electrical system. At least the O'rielly's I went to did.

You didn't answer my question about whether you had turned on the ignition to test the lights before you reconnected the MAF sensor. If you did, that would explain the CEL and Check VSC, which would go away after the computer realized that the MAF sensor was now working reliably.

Based on what you've described, there is no reason to suspect a fault with your alternator. While a bad alternator can cause a CEL, so can a plethora of other conditions, and the one that makes the most sense in your case is a MAF sensor fault, caused by powering on the ignition while the sensor was unplugged.

when i turned it on the car would do the check complete, then the check VSC would turn on, after about an hour the VSC light turned off.
