Hey all, Well against advice, my Mondeo ST200 went into the Ford garage today for a service. One complaint when it went in was a slight mis-fire below
3,200 (when the secondaries kick in) - fine above 3,200.They called me up about 1pm and told me its the HT leads. Fair enough. They are after all 6 months old!!. They are causing tracking on the sparks apparently. No problem, I will get a refund from the parts dept on the leads.
Then they said the HT leads are not the problem, but replaced the 123 leads anyway due to the tracking on the sparks. The 6 sparks where replaced as well.
So I pay my £299.97 (yes, you read that right), and go find my car - complete with the mis-fire still in place. But oh no .. thats not good enough for Ford. Now it's back-firing ! Popping as I give it some WOT. Also the car litterally takes about 30 seconds to get to 10mph. Given this is a 2.5L 200bhp car - I'm thinking thats not quite right.
"sounds like a dropped valve sir". Anyone describe what this is?
I'm no mechanic, but surely replacing HT leads, sparks, fuel filter, pollen filter, air filter and the other usual stuff on a service can't cause any imenent failure (if indeed it was!) to suddenly come forward?
Last time I ever take my car there. They got it over night so they can look at it first thing tomorrow. I'm hoping that they've just put a plug in wrongly, gapped it wrongly, lead has come loose or something simple like that.
Any thoughts on what they might have done (or not) ?
