116i slight miss

[12dan34]

Hi, my wife has a 2009 116i with the 2.0 petrol engine. It's done 118k and is generally really good, drives love!y and condition is great. Over the last year or so though it has developed what appears to be a slight miss when the engine's under very light load, we put up with it until now but within the last week changed the plugs and coils in an effort to cure the problem. I took it for a spin afterwards and was really pleased, thought I'd cured the problem, then when I pulled into our road, the miss, it sort of kangaroos a bit until you let off the gas altogether or floor it.

Any ideas please?

Thanks.

It's an N43 so injectors are the normal woes.

Perhaps add a container of injector clean up?

Thanks for your replies, I was beginning to think injectors too. Apart from this little misfire / hesitation, it runs and idles fine though..?

Injector cleaner, then a few tanks of Shell V power, see if that clears it.

Thank you I'll try that.
