1.8 Duratec Rough Idle Grr!

[b44dam]

hey fellas,

bought a 1.8 duratec 2001 mondeo yesterday, all is fine except somestimes it hunts a little,

when first started idles hight like normal, the the auto choke cuts out like normal, idles fine, then after about 5 mins the revs fall down to just below 800 and it starts to hunt a little bit,

if you rev it, it will idle fine, then after a while go down to 800 again.

another think i noticed, when i rev it and let off the revs take a while to come down.

Seems fairly common on this age of Mondeo (mine included) that they benefit from new plugs, leads and coil pack. Mine was a bit rough and hunting when I bought it and changed above and it was fine. Just started to hunt a bit at 2k rpm again but it did have an eBay special coil pack on so now looking at getting a better one. Hope this helps

i changed the coilpack for a genuine one, new set of plugs, still dont seem to have changed it, i was thinking maybe the idle control vale? when i un-plug it, it makes no diffrence to the running of the car what-so-ever. adam
