After posting this afternoon about my car's idling problems yesterday.

I was on my way home tonight. and hit a puddle .

everything was fine until a couple of miles further down the road, when it started to misfire.

I had another ten miles to go so limped home.

When i looked under the bonnet everything looked fine. have sprayed leads and coil pack plus connections with wd 40.

But it still runs lumpy, i have taken the plug leads of 1 by 1 and fitted another spark plug to see if one wasn't sparking, all seem about the same.!!

Any advise would be appreciated.
