On some cars the manufacture use's a MAF what is used on the Magnum 3.5l H.O. to read the in coming air

 

Throttle position. It uses the TPS to reference a lookup table for fuel and spark advance and then adjusts those inputs based on O2 sensor readings, MAP, etc.

 

Do you know anything about the two O2 sensors in this engine,,,,,I can read and record the sensors and they seem to report very defferent readings, one is very active and the other is not as active ,,,I just wonder if this is normal.....
