Hi,

I got a bmw 320i e46 - 05 (m54 engine) i got a missfire on cylinder 2 and I have done a couple of tests, i swapped places with the sparkplug module and sparkplug with another cylinder, i also swapped places on the fuel injector but the missfire does not swap cylinder. Any help would be Great.

What is/are the code(s)? How many miles on the car? Is the fuel pump original? When was the fuel filter last changed? Where are you located?

I got a code that said the fuel injector was faulty so i swapped it with cylinder 1 but it was still cylinder 2 missfireing. The meter i currently at 220 000 km. I dont actually know about the fuel filter, i am located in sweden.

Thanks for response

There's no code that states that a fuel injector is bad. Remember that codes are symptoms, and not solutions. So, please tell us the actual code.

When there's a problem in the fuel system the engine computer (DME) can throw some odd codes. Typically, the fuel system problem is related to inadequate fuel pressure.
