Just had car serviced came home and light came on.Was not on before it was serviced. Could it be something they did on did not do when it was serviced?
check engine light on Told it is airflow problem What does this pertain to? on 2004 GMC Envoy
what type of service did you have done?
return to the shop and ask them to check if they left something undone. have them check the code and see if it was related to there repair.
