Mondeo 1.8 pinking

Broken cat?

Chris

Change the leads for genuine Ford ones.

Spark plug leads. Not guaranteed, but fairly safe bet.

Made it the 100 miles back to Suffolk ok but not nice. 70 flat out down hill and 50-60 on hills. Held it just below the point of pinking. Going any more just means power falls away slowly. If you boot it, power just disappears.

You. Try servicing it.

So when was this bag of s**te last serviced?

Sept 2008. Not very helpful Conor

I have mine Main Dealer serviced regularly, but I still get a flat spot around 112mph.

I agree he's not.

Mine developed this twice in it's life - the first time was a deteriorating coil pack and the second was a broken and disintegrating cat. The coil pack was exactly as you describe it.

Just a note to the OP. If the coil is knackered and you continue to drive the car like that, the unburnt fuel will knacker the cat anyway.

Ditto if it's the plugs or the leads.

Mine does that too. Open the plug gap and polish the windscreen. :)

Thanks folks. It did the 100 miles back to Suffolk and that is it. No more driving until its fixed. I drove it very slowly in lane one and below the point when it pinked so hopefully not too much damage. I have not got time to fiddle so its going into a small reliable local garage this week. If they replace the coil pack/plugs/leads and then insist on replacing the cat I won't argue thanks to your advise. Hopefully the cat would have survived 100 miles of gentle motorway driving, but I have little experience of this as previous car was a Sierra and a cat, pas and other modern things are new to me.

I had a look under the bonnet thingy and the plugs are well separated already. :)

Odds are it's fine at the moment. Not that plugs, leads & packs are any cheaper :-(

And why do the coil packs deteriorate???

Just to wrap up this post. The problem was a disintegrating cat. Cat broke up and blocked silencer so that was replaced too.

Thanks to all for help and advise

Rockingrabbit

Pleasure.

As a matter of morbid interest if you dont mid what did the new cat cost? Mine was £300 fitted but that was a company car and they liked to chuck money at the garage that liked to fleece them.

Glad I could help ;-)
