i recently took my car to the dealership for a val. gasket/replace. now when im driving over 40 mph and dont down **** / just put it in neutral / my rpms drops then cuts off. any ideas? just wanted to know before i take it back (people at my closest dealership are F*ing retards)

 

Air intake.

Put the stock box back on.

 

what does that have to do with it?(just curious) i think it had somthing to do with my MAS, because i ajusted it alittle and it doesnt do it anymore. . . . thanks tho

 

That idle speed looks normal for A/C off. Should be higher with A/C on.

Your car sounds pretty normal. If it's a manual, the knocking noise from tranny is normal too. I don't know if the AT's make noise.

 

Just my .02 get someone to bump the idle for you and do a relearn like previously mentioned. Really smoothed my car out. Probably needless to say but with all that switch parts out, make sure everything goes back on in the right spot with out leaks. gl.
