Strange noise - Hard to explain

[Rogue]

Ok, this is going to be a weird one, but I'll do my best to explain it.

I've noticed recently, *sometimes* when i first start my car, or i'm sitting at idle in traffic, I can hear a weird noise coming from the engine somewhere.

All I can describe it as, is when you finish drinking from a milkshake at maccies or something, and you get the sucky noise at the end when there's non left - it's like that lol

I sounds like somethings trying to be sucked, but it's empty basically. I've checked all fluids and everything seems to be topped up.

Ideas? inky:

air-con system low on pressure?

 

[Rogue]

Shouldn't be. Aircon was service 3 months ago, and it's still ice cold.

I'll popping out in a bit, i'll try get a video to capture the sound.

is there air in the cooling system?

 

[Duli]

fuel pump on idle does that sound, its making it on mine and some other rs200 that i know of from new.

Good stuff. Thanks very much.

It was annoying me more than anything.
