Right... as i worked last week Friday I got Tuesday off and taught id sort my mums focus out. went to ford and priced up a set of plugs and leads... they wanted £104 for them, got them from my local motor factors for £29 (the ht leads aint bosh ones). Now with the new plugs and leads fitted it seams ok but i can feel a vibration at idle which i don't recall feeling before and its still coughing and spluttering now and then. Ill have a look at the invoice for the ignition coil and see if ford will replace it under parts warranty.
Im not sure if its connected in anyway with the EML coming on, but i looked down the leads and 3 & 4 looks good BUT 1 & 2 had what looks like green corrosion in them, not much but enough to notice it. cleaned them out with contact cleaner and lead 1 is cleaner than before but lead 2 still had green in it. the old leads are currently sat in my tool box at work so i can show the other lads and get there opinion on what they think.
Iv been in contact with my old work mate from the Leeds Jaguar dealer and he suggested, plugs and leads. After replacing them told him what it was doing and he suggested cleaning the throttle body out which i have done a while back, changing the fuel filter and putting some fuel additive in. I told him it doesn't have a fuel filter and its been run on shell v-power since we bought it in November 2011
Any more ideas?
