I replaced all my o2 sensors and still get codes. Often, accompanied by P0100 code (MAF). This morning the car stumbled, I got P0100 at first then after a few minutes P0130 P0150 (sometimes I get the rear ones too P0136 and p0156). On the other hand, sometimes I get P0130 and P0150 and it takes a while before p0100 shows up.
I ordered a new MAF, do you think that will solve it?

It is possible. Having a very rich OR most likely a very leam mixtire can keep the O2 sensors from tracing properly.

Thanks! This has been puzzling to say the least... First the car was not running right but without CEL, but one of my catalytic converter had burnt. SO, I decided to replace all o2 sensors (160kmi... I know, lesson learnt). First I replaced the two rear sensors only and started getting fault codes for the front sensors - strange. I called Bosch and they said that can happen with old sensors not working together well. So, I replaced the front ones a few days later. The car runs much better but I continue to get codes, now often with P0100 as well.
So, I went from a car that was not running well without CEL, to one that is running much better with CEL. I can't wait to get my new MAF.
