Engine revving when idle... (Mk3 Mondeo)

[Makhaira]

I had a similar issue a few months ago and it was just a pipe split again. It was down the left side of the engine, there's a row of 3 small pipes attaching to the engine, one of those was the culprit!

If it IS this, then you'll get the "hunting" all the time at idle, since the engine will struggle with air control.

The eratic idle on my Mk3 2.5 V6 Ghia X was also down to 2 split air pipes, but they were replaced very easily.

What do you mean by the hunting?? Mine has an ok idle it's just high revs and when you start it, or put it in neutral or brake then it revs to around 4 - 5 thousand RPM. Anyyone suffered the same issue, if so which one of the many pipes in the engine could it be???

That's a different problem altogether. Sounds like a stuck throttle of some sort. I'm not mechanically minded in anyway apart from the little things though, sorry
