Been trying to pass emissio with kooks longtubes and catted h pipe. I have foulers and they work, but the problem is car keeps throwing p0133 code if i clear it 10 miles later p0135 comes on wtf any ideas
Well the 0135 code is a heater malfunction on an O2 sensor which would lead me to believe you need a new sensor. As for the 0133, that needs to be corrected by your tuner by changing the timing delay or something like that due to the distance the sensor is compared to the stock manifolds. The tuning plays a big role in passing emissions but so does how you drive. You need to stay fairly light on the gas pedal to get everything to set and pass correctly.

And when I was doing my driving to get all of my emissions codes set I basically kept the car under 3000 rpms the whole time. No foulers used and I was able to pass.
I passed with no egr, evap ready lol
