Why are my vsc and check engine lights on now after grinding gears?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Assuming due to "grinding gears" that you have a manual transmission in your Corolla. I do not see any correlation to accidental grinding of gears and having these warning lights illuminate with poor power. Does the engine rev freely with the poor power? Too hard to know what's going on without hands on testing; initial gut feeling indicates a clutch issue -- but the warning lights coming on as a result of too much revving. Hands on testing is needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
