on the way back from cheltenham to cardiff last nite and about 10 miles from home a few bangs from the engine occured
so i pulled over and stopoped the engine checked all was ok then started her up agen
the zx was missing like no mans business
so i had to make the further part of the journey running off 3 cylinders

any body know how this cud occur and then stop???
ive changed all the plugs and found a suspect ht coil but i cant seem to get it to miss agen so i can check if its problem solved!!

few bangs - like backfiring - or from exhaust ?
- could simply be a Coil missing the connection on it's plug.
Now gone as you have been there !
But it's known that these single coils are prone to fail - at elevated temp's only - nothing clearly found with an ohm's tester when cold.
Try let the engine idle - then heat the suspect coil (or each one in turn) with a hairdrier. It takes quite a while before the heat propagates thru the coil. Don't melt/burn the coils though !

checked all coil plugs were on and they were
there was a suspect coil
it wudnt stay put wen u pushed it in it wud move out and release it self from the spark plug with the engine movement
ive ordered a ht coil from citroen so i can have a play and see which one it is but id put my money on that one!!
another question ... can u use some sort of cleaner on ht coils inside the rubber part and outside if so wat?????
