Please post some OBDII codes! Increased Emissions can come form a lot of items. Cam sensor, coolant sensors, O2 sensors, Vacuum, on and on.

I am chasing a P0492 Secondary Airbank 2 - Drivers side. It is not the O2 sensor as I replaced it. I have no cracked air lines and vacuum lines test good.

SES never comes on at start-up it usually comes on after 15 minutes of driving or in one case 1 hour. The secondary air pump is not even on at those times. The pump works great and I have received only bank 2 which means bank 1 is working OK - which means airpump and relay are ok.
