Teach me about P2196, 2097, 2099,0420, 2187
2006 C2S with 150,000 miles. these codes come up all at once on my Duromatic and when I clear them they will reappear a week or two later.
Car runs fine all the time.

With so many codes lighting up all at once, what is the process of elimination to identify the real issue?
Any thoughts would be helpful.
TIA
Johan
