first of all i know its not a 406 but i need a bit of help with my Mi16 . i was driving home tonight and it started missing a lot ( its been doing now and again for the last 2 or 3 weeks but now its there all the time ) . it only happens when im driving and not when im just revving it ( its only when the engine is under load ) . i was thinking of spark plug leads may be on thier way out but my knowledge of petrol engine ignition systems isnt very good . i put new plugs in there about 3000 miles ago so i dont think its them . does it make a difference if i took the car for a krypton tune or dont modern ( ish ) injection systems need them cos i aint seem any garage advertising them for a few years . im going to put a new set of leads on her tomoro but can anyone tell me what else might cause it as i cant afford to spend much on her just before xmas . thanks guys

This time of year there's always a lot of condensation about, my first XU9J4 always seemed to be prone to it, after wasting my money on new leads I took all the plug leads off, cleaned them and sprayed the buisiness ends with ignition sealer* and all the sillyness stopped. When my second one started doing it I cured it the same way.

*if you spray the whole engine as the makers suggest it looks awful and you can never get it off again

very true, the xu9 ingnition system is pretty woeful as its italian

problem solved , it was my distributor cap . the contact inside was broke so a new one for £18.50 has got it sorted and she's running sweet as a nut again

Splendid!

has fond memories of knackered carbon brushes and tracking dizzy caps...

Ahh, them were the days
