I purchased a new throttle position sensor, and am going to mount it on the tang of the throttle body. Should there be some spring tension on the sensor itself, of should the inner portion turn freely, without resistance. I want to be sure the new one isn't damaged. Thank you

 

Its good, just make sure it lines up..

 

It seemed as though it was under tension as I mounted it, but the inner insert freely now turns 360 degrees. Is that normal? TIA

 

I pulled mine just to check and mine does the same thing. Fire that puppy up!
