Rogue's NA Tune is shipping soon and I wanted to test my late DME to verify that it's in good shape. Since I have an early car, I also installed a late AFM I've had sitting around (because late DMEs need late AFMs).

As you can see in the video, it runs like garbage. It barely holds an idle, and I wouldn't dare drive it like this. To me, it really smelled like a bad AFM, although the AFM was pulled from a running car. I just want to get feedback on which of the two is the likely culprit - the early DME and AFM work flawlessly so it's definitely one of the two.

My understanding is that a good DME is needed to start the car (which means the DME is good). Is there any probability that a portion of the DME failed that would allow the car to start, but just run like crap? I'm hoping it's just the AFM, because the MAF will replace it anyway.

Afm sounds dead. To confirm, unhook the connector and see if there is a change. No change confirms afm is dead.

Thanks Doug. As soon as I get the NA tune kit in the mail I'll know for sure.

Just wanted to update this for the sake of anyone who stumbles across it in the future with a similar problem - DME was fine, AFM was bad.
