I have a Hatchback Rover 400, year: 1999. So far it has done 89000 Miles. I bought it last June and never had problem with since apart from recently. Whenever I drive over a paddle of water, the accelerator stops responding and starts dropping until the whole engine die off. I leave it for 10 minutes, then I start the engine again and it will start immediately. I really don’t know what is the problem. However, I presume it is to do with the water getting into the engine as the problem occurs only when I go over a paddle. I asked few people. They thought that there is an electrical problem. They believed that the water gets in the engine and goes to either the alternator or the Cap which cause the engine to stop. One of them actually suggested spraying WD40 on electrical components and wires, which I did. But, unfortunately, nothing changed.

I will be really grateful if you could lighten me with some solution regarding this issue before winter gets in, then I would be having a real problem with it.

I look forward to hearing from you.

Thanks in advance

Ben
