I was wondering what could be wrong the check engine light is on, i replaced the o2 sensor and it feels like my car has no torque. When i am already going fast it hauls ass, but it doesnt pick up speed like it use to, is there anyway to check what might be wrong? could it be something like the spark plug wires ? any ideas thanks
318is is running like crap

Check out the Fuel Pressure Regulator. If like my 328i that had oil in it that could be your problem. in addition you may have an intake manifold gasket blown, or the oil diffuser gasket may be blown (i am told that's common) and your vacuume may be f'd up. You might want to obtain a fault code reader to help dianose and read the fault codes.
Just suggestions.

Under the vehicle (drivers side) there is a heat shield held in place by 2 cap nuts and 2 std nuts (10mm). Remove the shield and you will find the little fuel pressure regulator that is held in place with a clip. E-mail me at [email protected] and i can send you a picture of the fuel presure regulator.
As for an intake manifold leak or the oil diffuser gasket leak you will need to have a leak down test performed and a compression test. Those 2 tests cost me 278 bills at a shop in Michigan.
They concluded from the tests that my compression was within specks but found the leaks in the intake manifold and diffuser from their experience with other bmws.
Suggest you shop around your home town for labor hour rates. I would avoid the dealership as their labor rates are generally 40 bucks higher than an independant shop that specializes in German vehicles.
Good Luck
I discovered my problem is that RMS sent me 36 lb fuel injectors, should have put in 28 pounders.

could it have something to do with the aftermarket intake i put in my car? Because i dont have an air box anymore, its just a adaptor and a filter on it. My car does leak a little bit of oil but i dont know where it comes from, and sometimes it leaks and sometimes it doesnt, it comes from the front drivers side of the car, well around that region
Also does anyone know why the gas pedal on my car sticks sometimes , it feels like it is hard then all of a sudden it goes, this usually happens when it really is running crappy, like no torque what so ever, I cant even peel out in it, I rev it all the way , then pop the clutch and all i get is the wheels gripping a little bit, It is driving me crazy
"check engine" might be caused from some more things 
...check the resistance with a multimeter -->
- of the injection nozzles
- of the throttle valve
- your air-velocity-unit
- your ingition coil
in most cases when the motor is cold an you drive with low rpm the motor runs good. if he goes warmer, you run with higher rpm and the motor runs retty shit it's a damage in your ignition coils (resitance runs up caused of increased temperature-> igniton voltage goes down)
Looky

Well i got the check engine light to blink and it goes on for like a sec or 2 then it pauses blinks again, then pauses blinks 2 quickly then pauses and blinks and pauses and blinks then it repeats it, does anyone know what this means? Also my car does seem to run better when it is cold, So what exactly about the ignition coils ? what do i got to do to see if that is the problem? Is that different from the spark plug wires?
