okay i havent drove my z for a while until yesterday when i took it out....

the driver side exhaust is making this popping noise whilst the other one isn't.

:headvswal :headvswal

 

i thought it would stop once the car is warmed up, but it didnt..

i have a bad feeling something is wrong.

 

any help/advise.

popping normally means a missfire maybe a plug on whatever bank the exh is for.only a sugestion.. :nana2: is the engine smooth running ok?

could be overfueling or running rich?

well i have just changed the plugs, maybe thats it.

its running okay, needs 02 sensor change which is getting changed on tuesday.

 

but this didnt happen before i done the service...

when is it doing it...when you lift off the throttle after hard acceleration ?

is there any black shit coming out the back? if its overfueling it might pop after youve been booting it the lifted off as the un burnt fuel is igniting as it comes through the exhaust ( i think) i know my 200 used to pop like fook

no black smoke..actually no smoke at all from that exhaust but its constantly popping, imean as soon as you start her up till you turn it off.

 

the other exhaust smpkes a little under hard accelartion but this one dont at all.

it wasnt like this a cuple of weeks ago. maybe before i gave it a service.

....but this didnt happen before i done the service...

Well, I know fook all about engines, but I'd start there. :D
