from time to time particularly after raining the engine seems to be running on three cylinders and won't rev up more than 2000.

on a sunny, dry day it runs perfectly. It doesn't sound like the high-pressure fuel pump issues that people are talking about

Somebody says to spray silicone all over the wires and I will change the plugs.

Any other advice is appreciated!

Many thanks, Tim Devlin
