I have recently purchased my E46 330 2001 convertible auto. I had to change the Camshaft sensor as this was presenting a fault code, the new one is now fitted and no code present. I also have replaced the original air box as the previous owner had half fitted a cold air induction kit without putting the inlet to the front of the car. SO I have put that back, however when i put my foot down the car seems to struggle to get going, if i put the auto box in to manual and put my foot down i get much the same results, no acceleration, being a 3 ltr engine i would expect a little more go than this is giving me. if i gently press on the accelerator the engine nearly cuts out, and has actually cut out on me. but if i press on the pedal with more pressure it doesn't do the sounds like it is cutting out. when i am cruising along the engine starts to change tone and sounds like it is struggling to keep momentum
I am new to BMW so any help or pointers would be great..
Thank you in advance.
