I have an 06 Cabriolet and I recently changed spark plugs in cylinders 2 and 4 because I had misfires a few days after replacing the housing for my coolant. Well hours after changing the spark plugs and ignition coils to cylinders 2 and 4 I could smell gas in the cab and a sound like air was being released for a few seconds after I turned off my car, not a whistle sound. I set my plugs to 22 ft/lbs (well, I used a torque wrench that used in/lbs and used an online converter to make sure i made the right conversion) with gaps at roughly .03. Just wondering if anyone else had this issue with an answer. I wanted to replace all four plugs and coils but the other two coils won't be here til 5/8/18.
