Have '98 Cobra, new to me. She throws a "check engine" every 100 miles. MY scanner (Konnwei KW808), says " Catalyst System Efficiency below threshold Bank 2". Car has No Cat exhaust and K&N air filter. Car runs fine.
What is the scanner telling me? What spark plug should I use for normal driving?
Any help appreciated. Thanks, Kurt
