Hi, my gas pedal vibrates alot during like around 3000 rpm and gets very irritating on freeways and also causeing buzzing sounds.The vibrating dissappears after 3000rpm at around 70-75 mph. What i noticed is when im cruising fast and then let off the gas the gas pedal like jumps and the engine feels like its not stable like its wobbling. Could this be my engine mount? Also how often do you need to change your O2 sensors cause i heard it should be replaced like every year and my car stinks after i drive it hard could this be the worned o2 sensor? thanks for the help.
