About two weeks ago I replaced my MAF, but I haven't had the ECM reprogrammed w.the recommended software.

A few days ago, my car threw an SES on the freeway. I had it scanned and got five O2 codes, for high voltage/slow response for the different sensor/bank locations.

I know that the new MAF does tend to run the car a little richer, so I'm not sure if these two things are related?

Thanks,

Noob out.

 

Need ..........moar...........vehicle............info.. ........pls.

 

It's an '01 20AE, 108k miles on the DE-K. It is a five speed.

2Y001 MAF installed, no ECM reprogram.

What else is needed?
