04 Rodeo RA LX Sympton: Apparent sticking throttle

[hjtrbo]

Hi all,

[RA LX 3.5 V6 5 speed manual (LPG system not installed)]

Just picked up a Rodeo recently for my work (Sparky subbie) and just today it appears that the throttle was sticking between gearchanges. No more the 2800rpm with the foot off. I pulled over and I confirmed that the throttle was closed by checking the linkage and cable. I was able to replicate the fault in the engine bay by quietly bringing up the revs with the throttle linkage. As it was revving away I unplugged the TPS and it went nicely back to idle.

Any thoughts on my problem? Taking it to Holden isn't an issue but if there is a couple of easy checks first then i'm all for that.
Does anybody know the correct output voltage of the TPS voltage at idle and WOT?

Any assistance appreciated!
NP
