Hi

Can anyone help me with this issue that i have on my car?


I have a 54 plate E53 X5.


My weekend project was to change the front drive shaft and a few other parts on the suspension.


That went well and today when i was driving my car i noticed a new problem.


I was not able to accelerate quickly like previously.


The engine sounds sluggish and performance is poor.


Can anyone give me a pointer where i can start looking ?


Thank you
