    It will only do it every once in awhile and mainly on colder days ive noticed. But it has also done it in warmer weather so i dunno? What does it sound like in your opinion? Any ideas?

    You've got me. It's hard to say just from the video.

    Definitely not piston slap.

    In our culture obsessed with absurd excess, the Nissan Micra is my counterculture car of choice.

    Bring the original video to the dealership on whatever you used to record it, with a set of headphones.

    At least they'll know you're not just making things up.

    Mine makes occasional "Whooshing" noises while cruising at highway speeds with the A/C on. I've concluded that I'm hearing engine bay noises I'm not accustomed to, as the performance of the car is unaffected.

    For the record, this is piston slap:

    MetroMPG - Car is at the dealership for the week. Ill post results as soon as i have them.

    AlphaMicra - Funny because it sounds very similar too the problem my car is having. Just during acceleration and not sitting still. Do tell what you think the problem is since the only opinion youve provided is that it isnt piston slap.. 3 times.. btw, thanks.. i got it.

    Actually, I said it wasn't piston slap two times, the third time I posted a video for reference. The sound of piston slap is very different from what you're experiencing. Yours sounds like the sound the injectors make. As I already mentioned, the injectors in this car are very noisy, as is the A/C compressor, and with a lack of sound deadening material, you're bound to hear those injectors when accelerating.

    Alpha - did you listen with headphones on? That's not injectors ("tick tick tick"), it's "knock knock knock or rattle".
