ok I was hookin up my VAFC2 the other day and unknownst to me my friend that was helping me unplugged my MAP sensor, looked at me and asked if I had a check engine light. Of course, I didn't I revved the car, nothin out of the ordinary happened. This is my first Honda. it's a 00 CIvic si. And I got it in March so I dont really know too much about it. So um is that a bad sign!?

 

when you dont have the map sensor plugged in ti when you rev the engine it sputter really bad and shuts off...happened to mine

 

so if my map sensor isn't working and obviously my check engine light isn't working, what do I do about it?
