have been under bonnet this afternoon and managed to somehow move the tthrottle position sensor moved it back to where it was before now cant get it to stop fast idleing as if the throttle is sticking can someone help please

are you sue the throttle is sticking or do you mean it just idles high now...

 

if its stinking then go over it with WD40 .... if not you need to adjust the idle with the IAA....

no its not sticking as such its just idling high what position should the tps be with throttle closed

if you need to adjust the idle

 

warm car up...

turn car off

disconnect AAC

turn car on

adjust idle screw to 650 ish rpm

connect AAC

 

and bingo....

but if you do that and the high idle was because the cable or something was sticking you risk stalling.

there is a link in the page I sent you to the TPS... :)

all i did was knock the tps and it moved anti clockwise vey slightly and idle speed went up so i moved it back clockwise have i broke it

No you just need to reset it, use a multimeter to get a reading of .44-46v, unplug the tps feed, start engine, then plug it back in while engine is running, the ecu should then read it correctly. If you need to adjust the iacv, unplug, adjust the idle screw till just before stalling, plug back in iacv plug and the ecu will then take over the idle.

cheers budd will try tomorrow does the engine need to be at normal operating temp first so it dont fast idle when cold

Ideally for the iacv yes, needs to be up to temp. Setting the tps can be done cold as its an electronic adjustment, but may as well do both at the same time, TPS first though.

no... the tps voltage is taken either two ways, one with conzult or the other with a multimeter (as groover has explained) and that can be done with the engine off see the guide i sent you..

lol.. well then I'm wrong.. :)
