Why is my accelerator sloshed after my mechanic forgot to plug in the MAF sensor

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Well, no one is perfect. I'm glad they realized the issue and were able to resolve it! In my experience, when the check engine light is reset in a Subaru, it not only clears the emissions data but also its adaptation memory. It needs to run at idle for up to 30 minutes in order to relearn adaptation. That's right, your Suby actually pays attention to how it's driven. You could try disconnecting the battery for 10-15 minutes to reset the system. This can help the ECU relearn the correct settings while idling. If it’s still not right, a mechanic might need to do a thorough diagnostic check to get that pep back in your accelerator. Hope this helps!
