my BMW is not responding on Acceleration.

[dhajyaa]

there is a delay in response when i accelerate. when i press the accelerator my car is not responding instantly.

Even there are problems when i stop at the signal too.

[ammanat]

what you mean that the car is moving but not speeding?

if that's the problem then looks like there is something blocking or leaking in the fuel system

get that check first

[Aboudi]

Maybe a faulty MAF?

[zuluu]

this happened once by changing the fuel pump things were resolved.

if there is a leak in the fuel system then problems like this may happen it can be that the pump is not working also.
