Hi,

I have a 2006 2.0L petrol Duratec HE, when I lift off the accelerator and coast the revs jump up and down around the 2000rpm mark, it's especially noticeable when driving at higher speeds. Eventually the revs start decreasing and stabilize. I have cleaned the throttle body etc. and changed the T-map for a replacement used one. The car does seem a bit more responsive with the replacement T-map but I'm still having the same issue (with the old T-map it also used to rev highly around 3000rpm when putting it into park before stabilizing but that problem seems to have gone). Does anyone have an idea what the issue is? Could be that I need to replace T-Map with a new one or it may be something else altogether?

Thanks Paul.
