Hi All,Have an E34 and having the above problem.Wondering if anyone else has experienced it before and how it was resolved.Tried doing a search on the forums and didnt come up with any related hits.Need some help here.Notice that verytime the car is parked in heavy rain or after a wash, water gets into the sparkplug compartment and the car starts to misfire when i drive and its temporary resolved after the water is blown from where the sparkplug sits in.The mechs i checked with doesnt seem to know what the problem is though one suggested that i change the rubber seal under the bonnet cover and to see if that helps. Thought i get sound advise from the sifus here before i try any of those suggestions.Thanks in advance guys for your help.Cheers!
