My car is making a humming sound but only once in awhile. I believe it has something to do with the fuel system because when I engage the accelerator it goes away. Not sure what it may be. Car 2002 Boxster 2.7

Another question: I replaced the four O2 sensors are there any adjustments that are required?

There are no adjustments needed for the oxygen sensors after replacement. If you had a check engine light on it will need to be reset. You should diagnose that humming sound. AOS, belt or idler rollers, fuel pump failing if humming is in the front trunk? Just a start, check our articles for further diagnostic procedures.
