If it's worse with rain, it's likely spark plug wire related. Moisture can expose the weakness of cable insulation. This is just a guess, but it's related to the conditions you described. Either way, hands on inspection and diagnostic testing is needed and will pretty easily turn up the problem. www.repairpal.com/repair-shops
