    Q:
    How can you check for a restricted Catalytic Converter for the 2010 Chevrolet Impala? Posted by Verified Customer
    A:
    To check for a restricted converter, you can connect a vacuum gauge to an intake manifold vacuum source and note the vacuum reading at idle and when the throttle is quickly opened and closed. If the fourth reading is more than one in-Hg lower than the idle reading, the exhaust system might be restricted. You can Select Your Vehicle to see complete installation and repair tips.
