P0420 with Kleemann cat again!
I'm getting sick of P0420 that showed up from time to time.
Is there anyway i can add a resistor/simulator to the post-cat O2 sensor to trick the ECU?
M271 owners please fill in if you have the same problem!

I have come to the conclusion the code pops up depending on your driving style. Can't really get around it other than keeping a scanner in the glove box to clear it whenever the light comes on.

Exactly dude!
If I drive like a maniac, I don't get the code.
But, whenever I put it on cruise control over an hour, I always get the code.
...the car is begging me to drive it hard or what???
Well...if anyone know a way to add resistor/simulator to the post-cat O2 sensor, please fill in!
