E46 need help

[perryyip73]

I just collected my E46 2.0L 6 cyclinder japan spec. I came across few weird sound from interior and 1 from engine. Whenever someone sitting behind, there is a jerk jerk sound from the seat and door. Second, is the engine part, airflow sensor got "FOO FOO" sound once i step on acce pedal. Finally, the most weird one. Whenever i go from 0-60km/h , my RPM will easily reached 2500, but the car move slowly, like too heavy ass. I can feel the power is less than my sister MYVI. Eventually fuel comsumption also high , where RM50 can only go 200+ km.Hope someone can give me an advise on how to solve these headact problems.

1) jerk sound it shoudl be your gb engaging into diff gears, depending on how long your car has run your gb might need a recond
2) soudn foo foo, mine happens too, check the engine bay for any leaks in the pipe for you airbox, or your ac filter. cahnged my ac filter and few hoses and it was a doll
3) maybe should have your gb checked..,
