i have a 94 plymouth acclaim, recently I started hearing a rattling noise from under the car, it has gotten worse and the only thing that seems to be in the area of the rattling is the converter, i get close to the converter and the noise seems to get louder. is this common, a rattling noise and if so what causes it and what should be done to correct it. also, can a bad converter cause the car to loose power and hesitate on the freeway?
THANKS
