Check engine light flashing, several codes came up on obd II

Hello, just to be clear, the shaking and hesitating is what caused the check engine light start flashing. It is not the other way around. You have multiple misfire codes showing up, a fuel lean code also. This would mean to me multiple concerns, like cylinder misfires from spark plugs, coils, fuel injector concerns, and perhaps an oxygen sensor or air intake concern. Hands on testing is needed to find out what's going on. Do not continue driving the vehicle, as damage too critical expensive components like the catalytic converters may occur. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
