Panic - it doesn't seem to be the HT lead or the plug! :(

Have you removed the distributor cap and had a look inside it? It could be that the copper post which feeds plug number 4 has corroded or disintegrated, especially if the cap is old. Also look at the copper arm of the rotor arm. The tipof this can get pitted and worn because of the high electrical discharges from this across to the copper posts. My guess is the dizzy cap and rotor arm need replacing.

Hope this helps.

Hi all,

I think I've got probs. My 94 Golf 1.8 CL started running roughly over the weekend and I determined that the 4th cylinder (on the right as you look at them) was not firing. I got some HT leads and plugs today from my VW dealer (all the new HT leads are the same length, is that correct?) and despite having changed the lead and the plug of the offending cylinder, there isn't any difference.

I'm entirely capable of having done something daft, or drawing wrong conclusions, but can any of you good folk offer any advice. I think I'm in trouble, and I have a 30 odd mile trip to work tomorrow. :(

Cheers.

All the best, Angus Manwaring. (for e-mail remove ANTISPEM)

It's entirely possible that the plug is firing but no power is being produced because there's something else the matter. A valve may be shot. Not shutting properly. Broken rings. If you take all the leads off and crank the engine does it crank evenly or is there a point in each rotation when it seems to speed slightly? If so it would signify one cylinder is leaking from somewhere.

You could also check to see if the plug is actually firing by taking it out, reconnecting the lead, putting the plug onto the engine and cranking. It should fire and if it does it's likely that you have another problem. It's not an injection car is it?

The split hose was letting air in, making the mixture weak. That's what was causing the misfire. Your brakes will be better too.

Gents -thanks.

My step son (and hero!) found the problem. A rubber hose leading to the brake servo(?) from the engine was split. Holding that tightly stopped the problem, although I've no idea why. Many thanks for your kind and speedy responses. :)

Thanks for that.

BTW a number of phone calls to my VW dealer eventually revealed that the HT leads are _not_ supposed to be all the same length. :-/

They are replacing them.
