    My 2002 V6 ATQ (191K 29MPG Highway 23 City) was due for state inspection so I needed to come up with a fix for my P0421 P0431 CEL codes. I planned to replace both rear O2 sensors, but first wanted to be sure this wasn't due to poor combustion performance or an exhaust leak. So I put 1 bottle...

    Seasons Greetings To All! I did search with no useful results. Issue does not occur when car is garaged;only when parked outside for eight or so hours while at work.

    CEL came on with P0411 (I think I'm remember correctly) - SAIP incorrect flow or something like that. Here are the repair steps I took: 1. checked all vac lines. 2. removed air line from SAIP and tried to blow in it while cold - unable to blow air in which means the combi valve was closed...
