To maintain good idle and drivability under all conditions, other input signals are used to modify the ECM output signal. These input signals are supplied by the Engine Temperature Sensor, Vacuum Control Switches, Throttle Position Switch, Distributor, Manifold Absolute Pressure Sensor, and Barometer Pressure Sensor.
Does this answer your question?

There is a whole chapter on engine emission controls in the manual I have.

Wow Dave, thanks. I think it might answer the question about the effect that the A.I.R. has on the ECM, no mention of it in the description.

I thought that might wake you up, Can't I use something a little more palatable, like Quaker State or Valvoline.

This weekend I conformed that the air pump is blowing into the unfiltered side of the air cleaner. Therefore, if anyone believes this is abnormal, speak up!

The exhaust has been modified so that the tube that formerly went to the catalytic converter was eliminated and crimped shut. I don't know if this is going to throw off the air system and possibly affect my air/fuel ratio since there is more oxygen blowing into the exhaust manifold. Any thoughts?
