Problem overview

The Check Engine Light may illuminate due to one or more engine vacuum leaks. Our technicians tell us these leaks can be caused by damage to seals and/or vacuum hoses as a result of to much ethanol content in the gasoline. Affected hoses and seals must be replaced to correct this concern.
