My van just started to perform poorly. Every time i start it, the engine shakes, and it has no power at all. There is gas leaking out the exhaust pipe behind the cat converter, and there is white vapor coming out the tail pipe. I checked for air bubbles in the coolant overflow thinking it might be a blown head gasket, but no bubbles. Any ideas?? This is my only car and i need help really soon. Thank you!!

Do you have a check engine light and when was last tune-up?? Best check the fuel pressure with a gauge sounds like the injectors are leaking also could be the fuel pressure regulator

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
