2000 Buick LeSabre Question: Should a catalytic converter need replacing at 44,000 miles?



, Arlington, VA, August 13, 2014, 17:12

The exhaust sounds like metal rattling when starting and when the gas petal is pushed down. Is driving too little (3000 miles or less a year)cause for this to happen?

How can I be sure that a NEW CC is being installed?

    Could be loose heat shields. Verify , by asking for the old part back , and actually asking them to show you the new one on the car. OR find one shop with good references , that you can trust , and stick with them.
