So a former friend put vinegar in my gas tank im not sure how much but the car died one day and never was the same. I let it sit for a few months because of work now the motor is locked up. Anyone ever heard of this or anything I can use to unlock a motor without tearing apart?

what a friend right?

Could have hydro locked. Pull the spark plugs. See if that helps.
