Hi Guys,

New memeber here, was hoping to get some advise on my e46 convertible 318 03 plate, i have been experiencing a bad idle for about 3 months now and it is driving me insane.
My car starts and drives fine but when i am idling it is extremely rough, the exhaust spits and doest sound too healthy.
Strangly the car idles great when i unplug the maf sensor but obviously i receive poor mpg and power so would prefer to rectify the fault other than spend a lot of money on fuel.

I have also had a vac test which came back with no leaks, the ecu reads a misfire code ( according to my local garage )

What i have done: I have bought a new maf sensor,new coil pack new spark plugs and nothing seems to have worked, i am guessing it is a air flow problem as it idles fine without maf connected.

If anyone could point me in the right direction that would be great.

Many many thanks
