Fiesta Zetec idle problem (Help)
Lads Fiesta 1.25 idles ok when you start it up, but if you rev it up when it drops back to an idle it starts to rev up and drop back. Have changed the
idle control valve.
Anyone got any other ideas?
Cheers,
Dave

Have you tried just unplugging the maf sensor near the air filter?

Thanks for the ideas. No codes, also it's a mk5 maf is inside the air box took a while to find it. Think I may have found the problem a split
pipe under the air box, looks like part of the breather system connected next to the idle control valve. seems ok at the moment anyway.
Cheers,
Dave

Look down the front of the cam cover there is some breather pipes that go around the inlet manifold. They are common to perish and split and will
give you this.
