Yours has the gold one and the plastic one right? If so I agree you have transient boost. Does yours have cats?I'm away on holiday, but before leaving I managed to find out that the (new) boost solenoid doesn't click and the kickdown doesn't work again. I'm also 99% sure that my car has the transient boost kit fitted!
The main issue would be the kickdown not being activated!Very interesting! Is there a way to quickly test whether a TPS is defective? How did you "wiggle it" ...?!
Maybe reposition it and measure again? It should be possible to move and rotate it a little while screws are not tighten.The main issue would be the kickdown not being activated!
I measured mine with a multimeter, and then twisted it so that full throttle was detected, but not idle. One of the fuel pipes on my car impedes the movement of the TPS, so maybe check that out!
