WELL I JUST BOUGHT THE CAR 99' SI. RED
The stock airbox was off of the car. so i had the dealer put it back on
only problem is, the check engine light wont turn off.

anyone know the reset code or something for the 99 si. coupe.

btw it only has 70k miles

 

You can hard reset your ecu by disconecting the battery but it might not help if it comes back then run you ecu for codes with a paper clip

 

get an obd2 scanner and erase the code, go to like autozone and have them clear the code for you
