V6 Help

[tbag]

2001 2.8 V6. Hi all, Have just fitted new set of plugs, the gal seems smoother but will not run as good at lower revs or under load. So i have taken them out. No 1 3 & 5 are clean but No 2 4&6 are half black & half clean on the outer rim.Could this be the root of my problem. The only other thing i can think of is I filled up with tesco petrol.Any comments would be welcome. cheers T bag

Having recently changed plugs and leads on one of these, and found out later that there is a special tool for removing the leads... Did you use the correct tool for the leads? Or could you have strained a good number of them?

If this the Mk2 V6, it does not have HT leads.

[NikpV]

no - bus bars - used for carrying electricity in high current/voltage applications not bull bars (aka child killers :35: :P :P )

It has 6 ignition coils, each one mounted directly on its own spark plug, with the wire windings actually placed around the ceramic of the plug. That way there are no HT leads and no HT distributor. Each coil is triggered electronically by the engine management system.

 

I should also add that some of these coils made in early 2001 were of poor quality and as a result VW recalled all of them in the USA (they were across the VW range of cars) and replaced them with newer versions. In the UK Ford considered them good enough for Galaxy V6 drivers. The first sign of any problem is a slight misfire or rough running which when it gets worse puts the engine management warning light on and writes a fault code to the log of "misfire detected on cylinder X".

Have put the old plugs back in and all is ok, With the new plugs in there is no misfire but I can tell when I accelerate the perfomance is off. Have re-gapped the new ones, I will try again.
