You have two TPS 's.
One on each end of the fuel rail assembly.
The one on back is the primary I believe
and the one at the front is the secondary.
if I'm wrong, somebody please correct me.
I thought mine was bad again,
even though it's only been a year since Triumph brought out the new ones,
That or a pinhole air leak I couldn't find.
Took it in and they scanned it.
Seems my first throttle body had got itself out of sync.
Had the customary high idle.
I've since zip tied the TPS wires down,
where they aren't just floppin around in the breeze.
So far, so good.
