I have a 2003 BMW325I and all the sudden it just didn't want to pick up speed like it wouldn't shift then I came to a stop and it turned off I'd restart it and it would die again like it had no gas.
I hit the gas tank and it started but wasn't
running right the computer said misfire this
happen all like in 15 minutes the service
engine light had just come on.
sounds like fuel pump is failing ,or fuel filter is clogged, any of this will cause a misfire, that will go away when you fix the real problem. could be clogged catalectic converter also
So what can Ido to fix that is there something I can put in my gas to unclog it cause when I hit the bottom of it from under the car it started again.
Definitely fuel pump if you hit the tank an it started
