a few days ago my 9-5 went through a decent puddle and is now having a few problems. i have a performance air filter without a gaurd and it sucked up some water from the puddle and stopped a few moments later. the car was able to start and make its way back home but is still having many issues. I havent driven the car since but i have let it run for a little while in the garage. It is making a strange clicking noise and it occasionally shuts off. I checked the cylinders for water and turned it over without spark plugs in and no water came out but i did change the oil twice and there was a good amount of water in the oil each time. since the oil changes the car runs a little bit smoother but it still makes a loud clicking noise when i drove it around the block. What could be the cause of these strange clicking noises?
