hello, i was searching a few boards and noticed that there is an onboard diagnostics and thought id try it out because it hasnt been running great lately, but instead of getting an check engine light flashing i recieved a few codes where the mileage is usually shown, this is what i got:
P 1684
------
P 0301
------
done
then it went back to the mileage, does anyone know what this means?? any help would be greatly appreciated, thanks again and have a great day...
