There is an ignition control module on the side of the airbox. I keep them in stock if you cant get one out your way. It controls the coils and spark. Common problem.

I've had a miss fire at idle no codes no change after new plugs. I've been wondering if its the ICM how much do you sell them for?

I've got same car, same engine.
Although I don't have an answer for you I can say I had to replace my MAF last year, and my symptoms were engine shutting down whilst driving, inability to start car after this and blowing smoke.
So I'd assume if you were having MAF issues your symptoms would be somewhat similar as your ecu wouldnt be able to receive accurate data on air flow and would shut it self down to ensure nothing goes wrong, can't see how this would cause a misfire?
I could be completely off track but though my experiences might help

Just had this exact issue happen to me this morning, waiting at the traffic lights then engine shut down on me out of the blue. Tried starting it a few times and would shut down straight after soon as it started, so had to tow it to the mechanics.
They did the diagnosis and came up with a faulty MAF code error. Even tried removing the MAF sensor and started it up and the engine would run ok, at the same time whilst the engine running, we put the MAF sensor back in and the engine would shut down.

Having a new one fitted tomorrow, hoping that's what the issue is, a faulty MAF.
