won't stay running
 

02 lancer oz rrm intercooled turbo. The other day i ran through some deep water and when i would hit boost it would jolt alittle so i dried out my filter and my mas and everything seemed to be ok for a day or two until i was about a mile from house and my car stalled after i hit some railroad tracks and i couldn't get it started. So i checked over the car and still nothing. Until the next day i tried but this time i gave it some gas a it started but after it comes down from high idle it starts to run bad and today i tried to drive it and stalled as i tried to back out of my drive way. And now it barley stay running. Anyone out there who could help. Thanks

anyone help.
