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.
