it came on today on my 95 240. i just got to running the codes on the ecm and got 34 and 76. what are they and how can i fix them? i figure its probably just a sensor somewhere since the car seems to run fine, but i'd rather it be fixed and not have to worry.

34=knock sensor, replace it76 = lean fuel system. possible causes are intake air leakfront o2 sensorinjectorsexhaust leakincorrect fuel pressurelack of fuelmaf

that is in order of probability.
