Throttle sticks for a nanosecond while changing gear
Throttle sticks for a nanosecond while changing gear was created by Hogweed
Posted 6 years 2 months ago #187754When I change gear, the engine revs momentarily when I lift my foot off the throttle and declutch. I find this moderately annoying. Now, on some other cars I’ve driven (eg Ford Focus – early 2000’s petrol and diesel), they all do it, as far as I can tell – so, to me, it's a design fault, and there’s nothing I can do about it.
Does the TF (2005 model) do it too, or do I have a fault?
Thanks

Posted 6 years 2 months ago #187757A good lubrication - which can take a while to sink in can help.
Other than that you will be looking at a sticky IACV valve (Idle air control valve) which determines the air mixture on lower revs.
One final and easy one to try is a throttle position reset, which re-calibrates your accelerator and has helped when tickover is high.
IACV reset is on a you tube vid somewhere and described in the how to section on here.

Thanks. So they don’t normally do it then?
Wow – didn’t know we still had IACVs – thought they went out in the early 90’s. Or am I getting confused… (definitely). I'll have a look at the guide.
Tickover’s fine though

The basic design dates back to the mid '90s.

Ah, OK I don't think it's displaying those symptoms though - I remember it all from my 325i back then.
Thing is, on the Fords, it's a design thing (map or something), not a sticky cable etc, and this feels exactly the same - maybe I'm just over-sensitive to it, and nobody else notices...
