Pop when shifting

[eclipse13]

Tonight i was flooring it and when i shifted from first to second it poped really loudly. It has only done it like 4 times. So it doesnt do it all the time, just every now and then. Any idea what it could be?

Are you venting your BOV?

You probably just have unburnt fuel in the exhaust which ignites there. Nothing to be too excited about.

I got a nonturbo. Could it still be unburnt fuel. I am not really worried about it, i actually laughed when it happened, i am just curious what it was.

it could...usually an indication that you have something wrong in one of the cylinders or with timing/cams.
