A couple of days ago i washed my 1992 bmw 325i, that night my wife drove it and she said she smelled gas she thinks then when she went to drive it later it wouldnt start. It turns over and seems like it wants to start but doesnt stay on. I bought the car in May and have been using the sea foam pretty much every two months and i was told that the sea foam might have washed away a bunch of gunk that was in the gas tank and it went through my filter. Then i had someone look at it and they banged on the gas tank and it started up that one time, but they said they think my exhaust is clogged and my converters need to be changed. I cant imagine all that would have happened when the day before the car ran fine, SOMEONE PLEASE HELP.
