Ghost in my cylinders

Ok we know the usual coil pack spark plug but I have had a weird jumping from cylinder to cylinder drop. Started out as cylinder 4 not running. Checked loom connection, removed coil pack. Gave it a clean, cleaned sparkplug. Plugged it all back in. Still not working. Checked the injector with srewdriver ( wasn't working) could not here a thring. Gave the connection a bit of a wiggle Bobs you uncle. Took it for a spin. Zoom fast as you would expect.

 

As I returned home just as I was pulling in the driveway it felt like the cylinder had dropped again. Checked cylinder 4 and everything was working. Could here injector working. No problem. So I went round them all started pulling the pack lead out to find out what one it was.

 

Now it's moved to cylinder 6.

 

But the injector is working I can here it talking away. I have checked voltage on lead. And that's fine too. The only thing I have not done is remove the pack and plug. I suspect it just a big dirty in there. It got dark and it takes a bit longer to get to cylinder 5 and 6

 

But is there a ghost in my engine bay swapping the cylinder problems every time I get it working

Could it be the loom ? Or even something along the fuel lines. Strange that the cylinder problems move between cylinders.

 

Any one else had this problem. ?

    20 plus years of heat from the Zed engine bay doesn't help when it connections/terminals. Ideally a new loom will eradicate many current & potential problems, but is expensive. Failing that you can get replacement coil pack connectors and practice your soldering skills.
