Yeah, but there's got to be a way to close the circuit or something at the connector, right? Bound to be a way to fool the light

It's not quite that easy. The engine management system checks the Air Injection system by monitoring O2 sensor voltage during air pump activation.

When the air pump is running, the O2 sensor voltage drops dramatically. This is how proper air pump function is verified by engine management.

SO WOULD YOU recommend removing TUBE TO AIR PUMP AND SEE IF IT DOES IT OR WILL THAT CAUSE OTHER PROBLEMS?

Sorry for the confusion. Will 202 and I were discussing a different issue.

What I meant to say before is unplug the electrical connector to the air pump motor, as an experiment. If it ever stops raining here and is light outside at the same time (unlikely) I will pop the hood and try to locate where the connector is for you. This SHOULD be an easy test to do, provided the connector is accessable.

IS IT accessible?

I took a look. It appears the connector is on the back of the air pump motor. It looks like you would best access it by removing the engine compartment under cover (big black plastic cover). That cover is held on by 4 screws as I recall but don't quote me on that.

Well its been a while and got used to the dips at stop sign, but when I pressed the accelerator and nothing happened...worried.

indy hooked up to a machine and throttle body and electronic trans module he thinks.

I cleaned throttle body again and things are fine, for now.

When do you replace T.A. over just clean them?
