no 4th plug popped loose. can i get a small magnetic tool to remove any stuff inside the cylinder ?
or what if i shoved down loads of air from my air compressor, could i blow the dirt up and out from the cylinder

Aitr compressor only way unless you take the head off.

If you have a hoover could you not get some really thin hosestick it on the end and poke it down the hole just a botchy idea lol.

if you take it too a machine shop they will get it out and fit the coil.

they used a micro hoover on mine

for the sake of £100

get it done at a engine shop

Thanks for the ideas,

I'm at my girlfriend's so unfortunately without my tools, I can't even get the engine cover off to have a look!

Forgot to say that no dash warning lights came on, if that makes any difference.

It does smell slightly of fuel under the bonnet when running, which makes me think you could be onto something with a spark plug having popped out?

If that's what it is, once I've checked, am I likely to damage it further by limping to Northwest Performance (the nearest specialist), or should I get a tow? It's only 3 miles.

Cheers
