I left the car running with the air conditioner on for about 15 minutes today. When I got in I noticed the check engine light was on. Does anyone know if this is something to do with the airconditioner?? I killed the car and started it back up and the check engine light went off. Should I be worried or just drive it as usual.

 

GO to autozone or something similar and ask them to pull the codes. WIll tell you what is was complaining about.

 

went to autozone and they said that the car is to old to test, I know different, but I couldnt convince them to do it.

 

well DUH, you have an OBDI car, the only "testers" made are for OBDII cars (95 and newer)

you need to pull the codes yourself, get a paperclip and do this:

no need to blame autozone....
