At the beginning of the week there was a bad storm. I have an Injen cold air intake on the car which sits in the passenger side wheel well. i hit some big puddles and the car would spudder and cough and then die. this happened three times on my way home. the CEL came on the first time and remained on. The next day i changed the oil and checked the codes. i got a AFS and miss-fire on all cylinders. i cleared the codes and continued driving the car. the CEL came on that day but the car still ran pretty well except for a small slight loss of power and slightly rough idle (shaking like it wasnt firing well.) The next day on my way home The car made a pop/thud/ some ugly noise. and then white smoke was pouring out of the exhaust. i was able to make it into my parking lot and shut the car off immediately. i checked the oil and coolant to ensure neither had mixed. the only thing i could find was oil comeing from the tail pipe and leaking between the turbo and downpipe and i was mayb a half quart low on oil. Has this happened to anyone? please send me all suggestions. Thanks!
