Well obviously you have stuffed something up for the computer to log a fault.

You need to find someone with a diagnostic tool, plug it in, and see what the code that has been logged means.

I would imagine something to do with the MAF or VSV

forgive my ignorance< but would disconnecting the battery the reset the ECU provide a refresh of the thing, maybe it'd say "oh right< air flow seems stock now, fine to go as normal" ... ...worth a try ?

i would reset the ecu...

go for it...

disconnect the battery, and pump the brake pedal a few times to remove any charge from the system.

and hook it all back up again.

My guess is you switched the ignition on while the AFM was unplugged...

Open your fuse box in the engine bay, pull out the EFI fuse for 20 secs and put it back in...

Saves the hassle of resetting everything after battery disconnecting ;) ...

That's what I did in the same scenario. Accidentally forgot to plug the MAF sensor back in and it threw not only the 'check engine' light, but the 'Check VSC System' as well. I took the fuse option and didn't loose my clock or my stereo settings.
