Slight knocking on idle?

Recommended Posts

Hi all,

 

So I picked up my very first Zed last Sunday & absolutely love it, cannot fault it aside from turning the heated seats on with my elbow every 30 seconds ha-ha.

 

Sorry if this is in the wrong section - couldn't find a correct sub-forum for this type of issue (may be man looking instead though)

 

BUT... Ever since I've got the car and took it home I have noticed what sounds like a very dull, quiet pop from the exhaust every now and then and a slight clunking noise which sounds like its coming from transmission/ engine somewhere only on idle, the car idles at around 500 and feels quite rough every now and then.

 

I'm well aware that there are many noises you hear in a Zed which are perks of owning one of these fine beasts but I can't help but worry about it, I've seen many posts saying that it's related to the idle air valve of some sorts as the car feels like it wants to stall sitting there at 500RPM.

 

Just to add, it drives perfectly with no issues changing gear or booting it, it's just when it idles it sounds a bit broken.

 

Anyone come across this before & know any fixes other than "turn your radio up"?

 

Thanks :)

Whilst your idle is low, I get the occasional pop when idling too - I think that is normal.

 

hmmmm not sure that's normal at idle bud

Car idles at roughly 500 ish at the moment, I have absolutely no issues driving or putting my foot down just purely once it's warmed and idles low. Car feels a bit shakey & clunks every now and then when sitting there. Going to clean the throttle body / maf this weekend and see what that does for my idle, failing that I'll go to a garage to try up my idle

Uh oh! Hahah. Even the occasional random pop ? Oh dear. Something I'll worry about another day.

Putting the ac on usually increases the idle speed. Have you tried that?

 

I have indeed although that isn't really a fix, as I said, it's only at idle and perfectly fine driving just wanted some input so that I know if my car is going to break or not ha-ha

What's the oil pressure at idle when hot ?

 

Roughly 27/28 PSI on the gauge on idle after a bit of a drive
