Emission light - routine cause???
During normal driving today the engine light came on steady. Checked the usual - full tank of fuel (not recently filled), gas cap tight, no obvious loose connections under the hood. The only thing different today was replacing the spare tire just before driving off. (Removed for rust-proofing 5 days ago.) Any other culprits I should check before I have the dealer scan the system?
Thanks, Smitty
