hi guys, i got this problems on my car. has anybody got this and got it fixed!? thanks

 

Interesting info here http://www.renntech.org/forums/index...92-o2-problem/

 

Related to your air pump. When you start the car can you hear this pump starting in the right forward corner of the engine bay ? This electric pump supply air to the catalytic converter at start for converter efficiency. If the pump start it is normally a leak in the small sense lines on top of the engine. But the bad part it is possible to be related to a faulty diverter valve.

 

I had the same issue I had a huge vacume leak. First check to see if the pump starts up then check the hoses, also your dv's. Good luck!

 

Thanks everyone I will see if I have an vacuum leak!! I'm glad I join this forum!!

 

I keep this updated...
