Like Sean said this part can be replaced without a full top end. You must take the intake "T" over the throttle body off to get to the TPS and the other end of that harness. Getting that "T" back on will be the real challenge though.

 

Thank you Merlin, I will definitely try.

One side question for you Merlin, are you also a enthusiast of WW2 planes like me, Spitfire pic ?

 

Ok Rick. I will look at that. And yes removing is easier since no alignment is required.
