Strange Cut Off

[Bo0oSt]

hey guys this has been happening for awhile but it only happens when its really cold at night and the car hasnt been warmed up that much...so what happens is when i drive and dont accelerate that much it feels like something cuts out in the car like the motor disengages or sumfin (sounds weird i know) but the moment give it a bit n take it bak to like 0.0 on the boostguage the car drives fine.

Basically it like cuts out n then engages again moment i rev a bit harder ?

Any ideas ?

sorry about the description guys its really hard to describe lol

Can someone also tell me what pinging is and what spiking is?

Oh and anyone know a good mechanic workshop for skylines in the South eastern suburbs in Melb ? My usual mechanic is annoyin me doesnt knwo whats goin on half the time

Thanks

so when its cold it hesitates under boost?

if it doesnt pop and fart its a airflow meter.

if it pops and bangs and still trys to rev but is really rough its spark plugs
