Hi Guys
Well I had the K running, although roughly, for a few days. However, yesterday I had to be rescued from the hard shoulder of the M4! - a complete loss of power - no way will she start! Cylinder 3 is showing signs of poor combustion and the exhaust manifold, at this point, is wet with what appears to be unburnt fuel. Also the downpipe of cylinder 3 is not getting as hot as 1,2 + 4. Spark on all cylinders seems good, compression is 120, 120, 130, 120 which I guess is ok. Any advice would be appreciated. Regards Mark (photoman Confused

1:Bad connection at water temp sensor or at ecu.
2:Fuelnosle unable to close due to dirt.

And one more thing.If you have NGK plugs,remember that they are
toast if they have been wet one (of fuel) time.I use DENSO iridium
IX22 and replace every 40k km or 2 years.Buying them from
http://www.spark-plugs.co.uk/ for 7,95 £.

Hi Jarn,,,

Hey..."If you have NGK plugs,remember that they are
toast if they have been wet one (of fuel) time."" (standard plugs )

Could you explain this and why it is so for NGK ??

No i cant explain why and it is normaly not a problem
in F.I. engines.Maybe the seal between isolator and
center electrode is not up to the job?

The injector may be stuck open causing the #3 cylinder to flood.
