Check engine light came on,we changed mass flo sensor & air filter. Light still on

Hi! This is Bo with Car Genius at RepairPal! This sounds frustrating! Have you cleared the light each time you've performed a repair? You may want to have the codes checked and diagnosed in order to save time and money. Once a repair for a particular code is completed, the tech will clear the code and then take the car for a "readiness" test drive to verify if the repair did the job. If you have any other questions feel free to give us a call at 877-913-1554! We'll be happy to help or find you a certified shop in your area!
