well i'm a noob to cars, and i just got a 96 merc tracer lts... so i was tryin to take apart my airbox, but half way thru, i had to go run an errand (so of course i had to put it back together) i didn't mess with anything other than pulling the plug on the MAF (or maybe it's a VAF? i dunno, tell me if you can) and then disconnecting the hose from the airbox. but now when i turn on the car, the check engine light turns on a couple of sec. after i turn it on... what can i do???
