Citroen XM Forum

My 1992 Prestige is misfiring. New HT leads, cleaned injectors, new plugs and a new coil but it is still only firing on 2 cylinders.

I have noticed that the wiring is badly chafed where it fits into the multi pin connector that pushes into the coil. Does anyone have this connector with a length of wiring attached so I can splice it in?

The car has been stored by me for 10 years and owned since 1996. It's a 1992 K reg Prestige 2.0 automatic (non turbo). I'll take some photos to show you more clearly what the damage is. I'd love to get it back on the road.

Thanks everyone.

A sharp knife, good quality flux, hot soldering iron and some fresh flex. Finished off with some nice yellow shrink wrap.

Hi

Have you tested or substituted the ignition amplifier? What have the wires been chaffing on? So long as they are not shorting out the damage shown won't cause an issue, I would just do as Rob has suggested and uPut some shrink wrap on but test the amp first, they are shared with a lot of pugs of the same age and the tct xm as are all the ignition components.

Very nice looking prestige by the way, that will be the 4th nasp prestige i know of on here, the how many left site shows about 8 in total left I believe.

Thanks. I shall take your advice.

The wires were chafing on a pipe. I will also fit a new ignition amplifier.

I shall let you know how I get on.

Dean was spot on. One new amplifier and full engine power restored. Thanks for the genuinely useful tip as I would never have known about this part.

After 10 years in dry storage, I have booked it in for an MoT next Monday. Luckily, when I laid it up I had Warners Citroen of Tewkesbury fit a new exhaust, callipers, discs, pads, LHM, radiator, coolant, oil and filter. So, it shouldn't be that bad. I shall give it a good service this week and see how it gets on once the garage checks it over.

Well I'm glad you sorted it out, best of luck for the not I'm sure it will be but a formality. Be nice to have some pictures when its on the road, it really is thevtwin of mine.
Out of pure curiosity what is the R.p number of your prestige, if you don't mind me asking?

I think it's 5445 but I'll check tomorrow.

I did have another identical Prestige until around 2006 but stripped it and scrapped it as there was little good about it. I've also had Series 2 saloons and Estates but will never sell my current Prestige.

It's 5665

I have also found all my new spares, many I bought over 15 years ago - side rubbing strips, front and rear bumpers, headlights, indicators, fog lamp units, genuine Cit XM rubber floor mats, aerial, radio, toolkit/Jack, wheelbrace and a windscreen. If it passes the MoT I shall do a complete refresh of the car. The wheels were new around 2002 to replace the originals which were a bit scabby on the edges. The tail lights and the wide Perspex strip on the tailgate were new in 2000 after a small low speed bump in Manchester airport.

I also have a new tailgate spoiler if ever needed and painted in factory grey but this is still vacuum wrapped from when I bought the car in 1996.

The only modification I have made to the car is the fitment of the two spoke steering wheel and deletion of the Prestige badge on the tailgate - this is replaced with the later style XM badge.

And a set of four sill jacking point plastic covers are in the glovebox.
