I get this code. Or I get the P0136. Every time. And I do mean every time that I start the car. Never fails. I believe mine is in the tune, not the sensor.

As long as the code doesn't affect the tune, I don't care much about the lightshow on the dash.

but whats wierd is that i had the weapon R antifouler on the car for about a week and it never threw a code...but on the ride home after the tune on the highway crusin at a perfect 14.8(lol) she popped on after about 150 miles

im thinking that the 14 hours of dyno time fried the secondary 02 sensor and thats why its throwin the code....

im thinking that the antifouler is working right since it never threw the cat below efficiency code....

so u guys think a P0136 is just a busted 02?

0136 refers to the secondary O2. It's not "switching". Check your secondary (B1S2) O2 and see if it's still reading. If it's not, or slow to read because it's too far out of the exhaust stream, that is why you are throwing the code. Been there, done that.
