The thing is, when you've got music on etc you don't really notice it. Sometimes it really irritates me and is VERY noticeable!
When I switch the A/C on, it disappears!!
The exhaust blows inconsistently, it directly related to the knocking sound. It's like the car is idling so lean, it's close to cutting off, hence the splutter. I really hope I can get to the bottom of this!
It's weird only people from Leicester have noticed this
Yes we definitely need to arrange something, it's nice to know there's more members from Leicester!
CS is always down for a meet also!
Now you have explained it in a bit more detail, mine seems nowhere near as bad as this its more like this... Hmmmmmmmmm-duf-hmmmmmmmmmmmmmmmm-duf-hmmmmmmmm lol but that's how it sounds making the noise about every ten seconds, it does not seem like its on the verge of cutting out and the exhaust is not blowing either.
Your description sounds exactly like mine, I think I was just over-exaggerating just to get the detail of the issue across
The 'Hmmmmmmmmm-duf-hmmmmmmmmmmmmmmmm-duf-hmmmmmmmm' happens to me also...
