Now that the diagnostics sticky is gone my light came on with codes 0705,0903,and 0304. Can anyone tell me where the site was that has the decoder, or does someone have a service manual they can look in and tell me what's up?

Looks like you're getting:
EVAP Control System
EVAP Canister vent control valve
Knock Sensor
Can't help you fix it but I bet doing a search on the above codes would turn up something. Good luck fixing it!

 

Thanks for the quick reply.
