Cadillac converter recall- when the Cadillac converter went out the car made a horrible noise and lost power to accelerate. Come to find out the pressure blew back and popped hoses of and broke the intake manifold. The flap cant open and close. Chrysler said that the intake manifold was not due to the Cadillac converter but teo auto macanica said it was. This is a $700 repair due to a recall! had been driving car around town all day. Stopped to turn and loud noise happened. Luckly coasted to blocks to house and had tow truck take to repair shop.
