Welcome,this problem is more than likely spark plug wires.You didn't say how many miles is on the current set,but if you have more than 80K on the clock this would be a good place to start.Dealer price is about $150 bucks(I think ).You can get a set from MSD or LMS so check on prices.When you install these new wires don't run them side by side with cylinders with close positions in the firing order as this can cause problems also. Good Luck
