ayte guys here the thing in 1st 2nd and sometimes 3rd, when i let off the gas, u hear a sould of a bov,!! :? , now if sure some air line is leaking but which one?,when i take it up to 4-5ths rpm’s i hear the sound, my friend i passed him and let off , he says it loud and sounds like a bov, sounds nice , but theres is prolly a problem and its gots to be fixed,
any suggestions??
sounds like a bearing…check out ur clutch fan those are known to go
My dad’s 94 Altima did that, if you redlined it in first gear and let off the gas really quick, you would hear it once in a while.
that’s sick yooo! sounds like a turbo! 
you guys should get turbo’s
i hear the noise when i rev high, i normally dont but ,i will check out the cluch fan
thanks
