after fitting new spark plugs, dizzy cap and HT leads my car was running fine but went out in it the other day it was only ruinning on three cylinders, after checking the plugs, i found that it was the fourth cylinder that wasent working, so i changed that plug for another new one and it went on three again uintl half way up the street when it burst in to life, but now no matter wot plugs are in it it only seems to be running on three.

if u can make sense of that then any help would be appreciated)

cheers chris

 

Is the dizzy cap ok ?

 

yeah should have said, it got replaced at the same time as the plugs n leads.

cheers

 

What colour is the plug from the faulty cylinder after a run ?

Im still thinking of a duff plug / lead or possibly a fuel delivery problem at the minute

 

was it fine before you serviced it? I'd say lead. try the old one.

 

car was fine before service, it jsut hadnt been done in a while,

it ran fine for a couple of weeks after the service, then just started doin this the other day.

cheers

 

does it only do it when ya start her up the 1st time during the day?

does it do it after shes firing on all 4, if you turn her off then restart?

 

finalluy got the chance to look at it,

the plug from the the faulty cylinder is black, in colour, soot deposits i think

diamonds - no, it does it every time you start her up, and it runs on three again if its been runnin on 4 ten u turn her off, but now the car wont start without a jump

sorry for very late reply, thanks for any help

cheers
