accelerator pedal/ flat spot

[Ahmed Bayjoo]

about 1/4 of the way down on my pedal there seems to be a flat spot, go past it and everything picks up again.

almost like a momenatry pause.

should i replace the accelerator cable or is it something else?

[drsmith1979]

check the routing of the cable to see if its snagged on anything or whether it has any play in it, new one is only 15+VAT from renault, easy to change too.

how many miles? service etc.. could be a sticking iscv or something, carb cleaner in the throttle body too may help a touch

Is there a pressure change then all of a sudden the engine feels much more free?

[Ahmed Bayjoo]

its on 108k and a service is due.

no pressure change, just as you start pushing down on the accelerator its fine, car keeps accelerating then you hit the 1/4 mark doesnt keep on accelerating just stays at the point you are, until u get past it then keeps on accelerating.

if your driving it enthusiastically you dont notice it because you past that point quickly.

its if your gradually accelerating you can tell.

:? hope that makes sense

1/4 revs or 1/4 throttle?

its not the second fly opening is it?

Most people dont realse the valver/williams has 2 throttle inlets and u can feel the point in the pedal when the second fly opens.

[Ahmed Bayjoo]

yes sorry its, 1/4 throttle.

im sure there has been a post recently in regarding the second fly opening up, was trying to look for that thread to post up on there .


i just find it too noticeable, my other williams throttle change was no where near as pronounced as this one.

just give the butterfly thing a clean?

this is the thread, can see the pis i put up of the body there.

cleaning and a new cable may help.
