Customer Question

Hi Eric
I hope that you can help me
I have BMW E46 318ci
it's stopped suddenly after start in the morning directly and i have to press the petrol for a second full (RPM) so it will not shut down.
and then after driving for a while it's become stalling and rough idle and you feel like it's dying!!!
the break becomes so heavy to goes down and from any touch for the break it will stop and you feel like the break is catching the car, and sometimes i need to push the break up with my leg so it will be a little bit normal.
I check the car OBDII
it's giving me secondary air mass relay and oxygen sensor bank2
i change the air mass sensor and it's still the same
and I changed fuel pump and break booster and it is the same.
many thanks in advance

Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
Having idle issues, hesitation, and brake issues at the same time, means that you have a vacuum leak somewhere around the intake manifold.
Can you check for vacuum leaks?
