Engine Performance problem
2003 Chevy Impala 6 cyl Front Wheel Drive Automatic 157000 miles
It just started 3 days ago and getting worse. OBD2 reads code P0420. From 20 to 50 mph it seems to have a loss of power when I step on the gas. Do you suggest with code given the catalyst converter needs to be replaced?
