Throttle Problem - will someone check this for me

[Harry_manback]

My car keeps going into 3k mode and having the electric fault light up.

i took the throttle body off tonight and realised it was vibrating like mad, almost like it was trying to reach closed but not making the limit.

so i without the engine running, but the ignition on i got my mrs to press the throttle and there is no modulation at all, just 0-100% open. where the vibration continues, like its quivering.

is this right or is my body buggered?
i was wondering if it was a bad signal from the pedal but i unplugged that and the body carried on doing it so im guessing its not.

Help apreciated..thanks.

its most likely going to be an internal tb fault mate, my cup kept going into limp mode when mine was fecked

thats normal mate.
i've been fooled by this one in the past.

with the engine not running pressing the pedal down you get nothing nothing nothing get to about half way down then it just snaps open..

the quivering is where its trying to find idle and where its not running it obviously cant..

they buzz too.

its one of those things you'd never notice unless you were looking for problems

+1 although i'd say i've never really seen a "quiver" tbh maybe a little vibration though. The buzz and all or nothing are 100% correct though, the megane is exactly the same too.
