LEXUS ES ENGINE

Took Vehicle To Toyota The Diagnostic Came Back 325. It Was Knock Sensors, Both Knock Sensors Was Replaced, Still Getting The Same Code....

I'm Really Not Sure On Milage But The Car Just Stopped Working When My Daughter Was On Freeway. And It's Been About A Month Now That It Sits...
