ok so i let my gf drive my car last nite. (97 accord mt 2.2 SOHC Non-Vtec) and she stoped at a light and when the light turned green she put the car into 3rd gear instead of first and it stalled out.. when she started my car back up the check engine light came on!!![]i have never seen the check engine light on this car so it freaked me out. i drove the car home and it starts, accelerates and shifts fine. but that dam light is still on and im hoping she didnt F anything up internally but from what i see and hear i dont think she did... what could it be? only thing i have on my car is an aftermarket cai...

 

check the OBD II code.
theres a bunch of tuts on this site that say how to read it.
post that here.
