have P38. petrol got flooded 3 days ago, managed to dry it out and everything works well except when started car water came out from the exhaust, starts and runs well but if I am going up the hill car is struggling, air filter got damaged and removed it, not replaced it yet as not easy to get it in where I am, also I can hear some shooting sound from exhaust, on and of, I am thinking of removing the exhaust to see if there is any water in. any other suggestions? bear in mind that where I am there are very limited parts available.
