Hi All

Thankyou all for your input.

I believe I have found the problem with my car which involved condensation,
looking around for different ideas from different groups i.e. "Brickboard"
for one other place to start, it appears a lot of people get there cars into
similar problems in getting there engines wet, either by hosing it out or
the rarity of my case water splash up.

Well this is were I found my problem and I guess any car that gets wet could
have any numerous conditions, I found my problem in 2 places.
There was some condensation in the dizzy cap only minor, however I did find
a minor pool of water in the connection plug to the coil located near air box
where a blue & red wire is contained in this connection after drying out and
using some electrical grease I believe touch wood I have fixed the
problem.well since I have done these things the problems have ceased.

Regards

Always learning that is for sure...

The idle speed is governed by the ecu. My guess is that splashing has fouled a connection (or shorted something) somewhere so the ecu is not getting the info it needs. Have you checked the fuel system? Otherwise, you're on the right track, Keep hunting around for the fouled connection...
