    97 328i runs rough until 3000 rpm.

    I've purchased this car with a slew of problems some easy fixes but I've come to an impasse and need some recommendations on what to check next. The car starts and idles fairly well which it wouldn't before I fixed the vacuum leak it had on the valve cover. It's just a little rough, and you can hear it in the exhaust kind of like a sputtering, until it revs past 3K rpm. I'm using one of those fix'd sensors I borrowed from someone because the car isn't plated. I've got a CEL with codes P0150 which is bank 2 sensor 1 O2(correct me if wrong might be bank 1) and P0101 which is generic code for maf I believe.


    I don't want to just buy an O2 sensor and want to hear if anyone has had similar issues and what fixed it. Thanks in advance for your help.

    I did that while running which I should probably switch them before and got p0155 and p0135 for circuit problems going to try this while off and see if I get p0130
