Running on 3 ? Help / Advice

Phil W · 18 Jan 2006 at 22:20

My Brother's R5 Campus Prima (1.4) is running on 3 cylinders.

He said it's only happened thought (conicidently when he was fiddling under the engine bay).

It's too dark to check all the spark plugs and leads, but its been a while since they were changed, infact we dont exactly know when.

Is it just worth getting new plugs & leads and replacing the old ? I pressume this is whats causing the problem ?

Cheers,

Phil

Fouth one is actually connected, isn't it?

But yes, HT leads do tend to break down, along with plugs. Might be worth swapping the known bad lead with a good one, then after, do it with the plug.

If the fault then shifts to another cylinder, you've got your culprit

How did you know it was only running on 3 cylinders out of interest?

You can tell by the sound of the engine, not so much on idle but when you rev/accelerate you can hear it, misses and sounds like its "jumping".
