I was on the hwy today and my car just cut off I did the codes and all I got was 32 so I played with te amf sensor and it started and killed again when I gave it gas, got the car towed home and now I cant not even get a code at all not even a flash from the check engine light. when I turn the key to the on spot/engine off the check engine light will not come on is that right or should it come on?

With the car in the ON position, the CEL should illuminate. If it doesn't, the bulb could be blown, or you blew the 7.5A IGN fuse in the driver's side kick panel.

First, grab some electronic contact cleaner, and make sure the connector on the wiring harness and AFM are both clean. DO NOT SPRAY IT INSIDE THE AFM!!! (never spray anything in the AFM, you'll kill it)

If it still doesn't operate properly, I recommend bench testing the AFM:
