Wet Weather Engine Cut Out

[johno]

For the second timw in extremely wet weather the Mistress has developed a problem ....

When driving in soaking conditions I get a misfire, followed by full engine cut out, only due to keeping the clutch up is the engine kept running. If I depress the clutch the engine cuts out.

It is obviously electrical, only happens when doing considerable speed and and when the roads are soaking wet. It has only happened on motorway sessions. Yesterday coming down the M11 late for lunch in Kent and pushing on. First time was coming back from ANglesey track day going to the Motorshow in the storm. Yesterday was much worse than the Welsh time.

After a while it sorts itself and then runs fine, but this took 20+ miles yesterday ....

Any ideas where I am getting water in ???

Just got it back from service so air filter shouldn't be an issue but I will not rule it out.

It does appear at speed ! So it does sound like that may be a possible reason. Cheers Apache.

Cheers Paul !

Decided it was a sueak being made by yours as describled rather than anything more sinister. Heard from Bristol yet ?

This is a temporary misfire only caused when it is wet and is in fact an engine cut out. This is not continuous running with a misfire otherwise I would not be using it at all !

It does make me laugh wen people say this and I then watch them turn their cars on too warm them up before arun and just let them sit there until they are hot. Good on the old cats that one !

Whys it not good on the Cats Johno, as i always like to warm the engine up a bit before setting of on my very short commute in the morns/evens.

Also did you sort the fault out??

When the car sits warming at idle the engine is running very rich and inefficiently. The fuel therefor not being burnt is being washed all over those Cats. It does help to knacker them. If you consider it, it is the same as running the car with a misfire. It is unburnt fuel reaching the Cats.

I agree I like to warm mine up before I drive it, but I do not let it sit there until it is up to temp at all anymore. I drive it at no more then 2500 revs until I hit minimum 60 degrees on the gauge before I go any further up the rev range. Easier for me living and driving in London I suppose than others ...
