GPX playing up, anyone recognize the sound?

Here's the link to a sound recording I just made:

Basically, I'd been having problems with low revs and the car stalling, so I did my research on here and it looks like that problem is the stepper motor. I ordered one from Ebay and am waiting for it to arrive. But last Friday it started making these strange noises and has been running rough and sluggish since, also chewing a fair bit of petrol and blows a little dark smoke when revved hard.

Any ideas? Have any of you guys had this problem before?

My brother thought it was the cat converter so he took it to a mate's exhaust place, they had a look and didn't think it was that.

Did you record from inside the car?

It's hard to hear much from that recording...

[vipfto]

hard to tell almost sounds like a coil pack arcing out

Agree ^^^^^^^
or a spark plug has gone, or even a lead come loss/ off.

i agree, definately a lawn mower, haha

my pocket rocket had more grunt and thump behind it hahah,

but yeah, definately check all coil packs spack plugs and leads and plugs etc, make sure all are corrected properly and arnt damaged
also check for water deposites in the leads and spark plugs

The recording was taken from outside the car, standing about a metre from the rear passenger side wheel
