which HT leads?

maxgreenwood · Post by **maxgreenwood** » Wed Nov 30, 2011 4:12 pm

I have today received from GSF some new HT leads for the GTi,
part no. 926PC0150

I'm wondering before i open them if they are correct.

These have the rubber plug 'surround' at the plug end designed to plug into a hole around the plug, as on my 16TZS, but the Gti doesn't have these holes, i'd say i'd have to cut them off with a knife for these to fit in the tight space in the GTi.

And the distributor lead ends seems to have generic crimpable clips as opposed to the snug fitting ones on the existing lead that push fit on.

Is this to be expected, to modify these leads slightly, will they work ok, or should i be looking at getting something more specific from Citroen, which will probably be more expensive?

Thanks
Max

You shouldn't have to modify the leads. I sold a set of GTi specific Magnecor leads to Tim recently and, if he doesn't want them maybe he'll sell them on. They were good. Otherwise, order a set of leads from Magnecor - they aren't that expensive and my experience is they are as good as - actually better - than the genuine Citroen ones.
They do an 8mm lead which is intended as a direct replacement for OE.

I'll second Magnecor - vehicles running on LPG place higher demands on the ignition system so they are quite a well regarded upgrade in the LPG world. It's apparently quite common to replace HT leads every few years to avoid problems when on gas, but the ones on our Discovery have given no problems in 8 years.

It seems like you've either been sold the wrong leads, or more generic ones which could be made to fit so should be possible to get a refund.

I fitted them to Xantia to try and help its poor running, it didnt and its still Fecked, (its driving me mad)

I may swop them back to the original ones as the rubber bung on the end that stops water getting inside the plug hole isnt fitted, and you know me an water!

Max if you look on ebay you should be able to get soem correct type ones which are a direct swop, the GSF ones are normally cheap generic types.

Is it worth me perhaps using these 'for now' to see if they cure the rough running, maybe getting some better ones later? I'm not sure I can wait 1 or 2 wks for delivery as it's doing my head in a bit.

It would be annoying shelling out on Magnecore and not getting it sorted also.

I could get some of them or something off eBay later.

they are this german brand:

Tim, out of interest, did you detect the little bit of sparking/flashing on the leads on your xantia before changing?

you can get the rubber boots off the new leads without damaging them,
as i have just done on a set of new bougicord lead a customer bought for his GS from Chrevronic,
i had to get the boots off to fit all the other protective sleaves,

i found if you put the tip of a very small screw driver into the kneck along side the lead, then squirt some silicon spray into the kneck,

this allowed me to easily slide the boots off without damaging them or the leads,

thats if you choose to go that route,

If you haven't already bought some Magnecor ones, we've got some Megaleads in (silicone, 8mm) at work that are less than £20.

Max I do find it - as I'm sure you do - irksome that you forked out good money for a GTi that has this problem. If the HT leads don't fix the problem, what next? Getting the injectors ultrasonically cleaned? Worry that maybe it's the MAP sensor or some such thing? My advice is get a professional to do a diagnostic on it; (I assume having electronic ignition you can plug something into it!) - trouble is I can't say how or who.

OBD is pretty limited on those systems. It's usually done with a box that has an LED which flashes in pulses, the pattern of which determine the fault code.

i have not/never seen a BX with an OBD socket,

well i've gathered now that i need 8mm leads without the water bung at the spark end, and with M-4 type connectors that fit snug around the smaller type pins in the distributor.

GSF Dublin sent me the wrong leads. GSF Belfast have been much more helpful and have organised to get the correct ones for tomorrow morning at the Dublin outlet.

I would get Magnecore, but it seems a long lead time, and i want to get some new ones on ASAP.

Max I do find it - as I'm sure you do - irksome that you forked out good money for a GTi that has this problem

I didn't notice it on the test drive, and it is slight, annoying at static throttle when in gear, don't think i did much of that on the test drive and the spheres were so gone i probably thought it was part of the car jiggling about. I gave him 3/4 of the asking price and considering the condition of everything else, i didn't think it was a bad deal.

A couple of people have suggested the throttle gets gummed up on these, and the revs always hover at 1500rpm for 3 seconds when taking it out of gear and releasing the accelerator, which my common sense would say could be something to do with that. It may be adding to the slight roughness in running too I guess. Any insight here would be very welcome.

I'll let you know how things go with the new leads...

From memory i think my Gti had a sticking throttle as well, a bit of cleaning & re-lubing sorted it

Hope your HT leads cure the issue.
