I have a 2001 Acura CL 3.2 Premium with 223,000 miles and it has been running fine but yesterday I went to the mall and when I got back in to my car to leave the check engine light came on and it was flashing. The engine seemed like it was shaking more than it should be and the exhaust was making a bogging sound. When I plugged in my scanner it read the code P1399 which is random/multiple misfire. My friend thinks it might be my catalytic converter but I'm not to sure. My question is has anyone else had this problem and does anyone know what else the problem could be or to confirm that it is the catalytic converter. I'm going to run to autozone now to go get some new spark plugs and a new air filter to see if that helps at all.
