Check engine light come on while driving. Started running really bad. I realized cataletic converter was glowing red. A friend unclogged it to c if that would fix it. Still has the same problem.
Get the codes read at a local auto parts retailer such as "Pep Boys, O'Reilly, NAPA and fix as required to clear the codes. Unfortunately I am not sure how your friend "unclogged" the catalytic converter, but he probably just created more codes from the O2 (Oxygen Sensors) and the Catalytic Converter to show up.
