I have tried a different drive cycle and caused .
my catalyst monitor to complete...which turned on my ck engine light and showed code P0420. I checked and found a couple of leaks in my exhaust system. I repaired them. The problem still exists. My evap monitor is still incomplete. Now where do check or look to find out the cause for this code?All help is appreciated. Thank You. Hv a happy New Year.

 

I have replaced evap solinoid, and leaking fuel line replaced, also found a hole in exhuast and fixed that. Now two incomplete monitors, evap and catylist. No check engine light. Would like to clear evap first if possible. What drive cycle should I follow to do that? All help appreciated. Thanks. Hv a gr8 day.
