1997 Lumina Engine Light

I don't know what to do, my 97 Lumina service engine light constantly goes on and off, however I've noticed that <b>every single time</b> it goes off, just before that happens, whether the A/C is on or not, I feel this gust of hot air come through my vents and the light shuts off. Does anyone know what this means, or should I just go to a mechanic. Please please help. thanks

Go grab an Autozone tech when its on and have him/her read the codes its giving you. That'll point you in the right direction...though I haven't a clue why it'll gush hot air unless there's a vaccum leak allowing the HVAC system to switch from whatever its at to heater.

thanks I'll try that today after work and get back to you.
