The gray/white wire is the one that needs the varying voltage. If it is constant then the TPS is no good.
Check for voltage on that wire with the connector off the TPS as well with the key on.
We are going off track here.

But the gray/white was the one staying in the 5 volt range. Tried with multi-meter set on 10 and 20. To see if any change. Wasn't any.

Okay, when you install it, do the same test and voltage should go up and down as I stated.

Okay, how you test it is to turn it off. Then turn the key on, back probe the signal wire and check the volts at idle and open to wide open and watch the voltage change.
The videos were not good. 3/4 of them were cut off.

Once you pass 1/3 idle the engine starts to rock back and forth. When I first tested it. It was a little over 5 volts at idle. But when you start to accelerate it still doesn't drop voltage.

You are not listening to me.
I said turn off the engine. This test is not done with it running. Just turn the key to the on position and test the voltage by moving the throttle on the throttle body. Again, the engine is not running.
Test it that way.

Okay, i.21 is too high. It should be.5 to.75 and 4.8 at wide-open throttle.
Can you adjust the sensor? Does it have slots on the sensor at the screws for adjustment?
