Engine my rolla back fires?!

my rolla back fires?!

i got a 00 rolla with a K&N filter and a TRD exhaust and it backfires.... not alot but enough to be hear. When u rev the engine it can be heard especially when i was messing wit the tranny today put it into L and went about 25mph and i let go off the gas and let it slow down on its own and as it revs down it back fires very quickly and often....

Is this normal?

sounds like you could be running rich...

Me too...occasionally when I drop it into 3rd to slow down I hear, not reallly backfire, but the exhaust sound skips. It isn't a smooth sound that starts high and winds its way down. Kinda like hiccuping.

Heh, you should hear mine at idle.

its normal mine just purrs evenly.

kinda happens to me too, u can barelllly hear it tho

mine does it when the car gets warm. it sounds cool cause i let off the gas and u hear it gurgle and pop. same setup too, k&n filter with trd muffler

i heard it cause i put my head out the window to hear it..... i also hear it when i rev it to 6k and let go of the gas and it does it a little too, its not really loud like on come civics i heard wit a loud ass exhaust

On Mine when you floor it and let go of the gas it does not pop it sounds a bit liek a motor cycle.

ya mine is like a combination of everything said so i guess its ok

the idle is 1200-1500 rpm for mine any lower and it will rumble and possiby turn off. and the fuel is continous in my injectors.

mine doesn't back fire... heheh... but mine is auto plus it is just axel back w/ stock piping but isn't it normal to hav back fire when u let off the gas or down shift... if it is normal then my car is f-ck...

backfiring is perfectly normal.. where did you expect that unburned fuel to go when you step off the gas? the injectors dont shut down instantly when you lift your foot, so that fuel has to go somewhere

my car does it little puffs of flame out the side of my car hehe

my car backfires (or at least it did when the engine was still workin), and i never really realized how loud it was until fastrolla was behind me one day, and told me bout it....personally, i like the sound....

that little gurgle pop sounds very mean, i get asked often if i got a v6

yeah i know, and when it get really low it sounds like a deep throaty sound on the exhaust. like if it was a v8. the gas on the other hand it uses quite a bit regardless. and thats because the injectors have all been replaced and it still does the same or it did when it was working.

mine is auto wit no intake for now

mine used to backfire... when my maf sensor fried.. it mad a pop sound after getting off the gas... and sometimes multiple pop sounds..

now that I replaced my maf sensor .. there is no sound at all??

man my car must be weird or f-ck in some ways cuz i got a home made intake to the stock airbox w/ K&N drop in filter and axel back ractive fart can but it doesn't back fire not even once...
