I am throwing a lean code on my bank 2, sensor 1, 02 sensor. I know I need a tune due to my spacer, tp's and k&n air filter but recently my car started puffing out blueish-white smoke if I blip the throttle sitting still, but it does not smoke at all if I go WOT. the lean code also came up recently so I'm wondering if the lean condition is causing the smoke or if something else is causing both. No vacuum leaks that I can find, and did a compression check last fall(just because), all was good there. Where do I look next?

 

Anyone?

 

Try erasing the code and then try disconnecting the b2 sensor1 o2.Should be 1st sensor on the drivers side header. see if it gives the same code. If so,may need to replace our o2. Let us know how it turns out.
