just about to lose my mind

I have been trying multiple things to fix an ongoing issue. I have a 01 325i that is struggling to keep up. When i first start the car the idle is extremely rough and often dies. Once i restart the car a few times and after it warms up it begins to run somewhat better. Even once the car wil stay running it is still lacking power and sort of surges when in gear with the brake applied. I have replaced both the intake and exhaust cam sensors. They seemed to help a little but this obviously was not the solution. I have ran a can of seafoam through the vacuum lines (which created a little smoke surprisingly) and I had also changed the plugs. Im sort of lost on what to try next. I had the car out on the highway the other day and once i finally got it up to 65-70 mph the car would make a rumbling sound when around 2200 rpm. if i would get outside that rpm range the rumble would stop???? This car is about to get the best of me and I am looking for help. A while back it starting to run crappy and finally took a dump until i replaced the fuel pump. Like I said im am looking for any ideas on what to check next before this car ends up wth the fishes.
thanks in advance.

Im think the o2 sensor or fuel lines cloaged causing you to lose pressure, but im not a super mechanic just a car lover.

Is the MPG/KPG poor?
I would clean the MAF, AND the Throttle Body before you start a fire !!!

Thanks for the replies.

I have also cleaned the MAF and throttle body, i have even pulled out the IAC vlave and cleaned it. I have checked for vacuum leaks and all else. The car to me seems as if it is running rich and sort of flooding itself out. Another bmw owner hear locally told me that he has heard something about the thermostats on the E46's may cause the engine to misfire when the thermostat is beginning to fail itself. This sounds a little strange to me but at this point im open to advice.

So I have given up, the car is going to the shop on Tuesday. I decided to drive it into work this morning and it died a few times when first started, finally would stay then it died at the first stop sign. got onto the highway and it had trouble getting ip to 55. Once I got into town it began to runa little better. One thing I did notice is that when at a stop sign and the car is in gear the idle is jumping around from 500 to 800 rpm.
a list of things i have already done.
new fuel pump
new plugs
new intake cam position sensor
new exhaust cam position sensor
ran seafoam through vacuum lines

so the mechanic called this morning and says that roughly 40 codes came up on the computer. he is looking at the plugs and running a compression test across all cylinders but it sounds like the car is going to cost more to fix than it is worth. I may end up getting rid of the car soon as i am fed up with all of the little problems that keep arising. this will definitely be the last BMW that i will ever buy.

looks like the compression is a little low on cylinders 4 and 6, around 135psi. both of these plugs were fouled as well. I guess im looking at a few coil packs but i would like to verify this is the issue before spending the money at a chance it may fix the problem. not to mention the shop got me for $120 just to tell me that the plugs were fouled and it was missing. I have also discovered that i have developed an oil leak and i beleive it may be the front seal. with 185k miles on the car i think i can let the seal ride out and just watch my oil level but the coil packs seem to be my first issue. does anyone know how to test these?
