can eney one help me with this problem my s2 3b has started to run lumpy i sprayed wd40 on cables at the back of the engine restarted the car and it runing like a dream a couple of days later then starts to go back lumpy eney ideas to what this can

What cables ? Sounds like it could be coil / HT wires or maybe a sensor wire you sprayed it on. If the insulation on these wires is shot then WD40 would drive out the water and temporally stop them shorting out and thus stopping the miss fire.

i spray it near the dizzy the ht cables are newish but i insulated them on friday i put a new coil on thinking it was that but its stil the same just thinkin may be could it be the hall sensor

[driftin jo]

yes it coul be, the insulation on the wires from it could be shot.

[orangepeel]

what do you think replace the wires and look for breaks in them or change hall sensor

Did you get WD on the idle control valve? It could be jammed and the WD freed it up for a bit then seized again.

I don't see how you could free it up without taking the hoses off as the WD40 could not get in but it could be moisture in the connector on the ISV.

Wait until it is dark out. Start your car and open the hood. Observe any blue sparks coming from the high tension leads coming out of the distributor.

Replace leads.

even if leads are newish i put some insulation on them all. a new dizzy cap rotararm looked ok

When you say you have put insulation on them do you mean insulation tape ?
If you mean standard electrical insulation tape this will not help if you HT leads are shot.
It is not designed and cannot cope with HT.

You shouldn't wrap anything round HT leads, it only makes things worse.

How new are your spark plugs?

what is the dielectric strength of the heat proof shielding you used ?
If the answer is you don't know then it is very likely not enough for HT.
