206 misfire

My peugeot 206 (year 2000, petrol model) has developed a misfire. i was
driving along fine one minute then it started to misfire.

symptons: lack of power, poor idling and misfiring (sounds like fuel is
igniting in the exhaust pipe but not loudly back firing out of the exhaust
pipe)

I have re-newed the plugs, checked the valve clearances, compression
tested the cylinders, checked that all the plugs are sparking.

Is there anything else i can check to rectify this problem before
reluctantly taking it to a garage?

Thx in advance

Try replacing the coilpack, it's a nasty one, its tendency to breakdown
at about 70-80.000 km is well-known, the ugly part is that it usually
fails only when hot, so when you test it out of the engine it seems
perfect.

Maybe you can try with a coilpack from a wrecked 206...

Or just re-seat the coilpack - my 206 (at 130,000 km) suddenly
deveoped similar symptoms and the mechanic "fiddled" and re-
seated the coilpack (I don't know what exactly he did, I gave up
fiddling with my cars when chewing gum and fencing wire no
longer cured problems) and exit problem, still OK after 10,000
km.
