CEL on. Says it's the MAF.

If the car is running ok, drive it until the CEL comes on again. Write down the error codes and check back. These cars are pretty easy to fix if you know where to look.

The AOS was changed last year. I am hoping its just a MAF issue.

- Somewhere around the last part touched is liable to be the problem. Infant mortality or improper installation.

- The part is new so must be another failure.

Get the codes. Post em.

I strongly suggest investing in a code reader or durametric s/w. Enables you to have some basis for troubleshooting or for you to learn how long a problem can be ignored or even how to talk to the service adviser and keep the expense under control.

1+ on the Durametric Reader.

If you had this tool, you would actually be able to see how the MAF is responding to the engine revving, and see if the MAF is bad.

That would then save you any additional guessing as to what part is causing the issue.

I wish Durametric make their software to cover other cars, like my gf's Crossfire, or my Altima.
