Misfiring (had diagnostic done)

[SP60]

Hi all

My Zed seems to be misfiring when sat on idle, I got a diagnostic done and here are the results. Wondered if any of you could point me in the right direction now.

DTC 279C -Thermostat characteristic cooling. Activation.
-Intermittent
DTC27C3 -Thermal oil level sensor
-Intermittent
DTC2883 -Mixture adaption, bank 1
-Intermittent
DTC2883 - Mixture adaption, bank 2
-Intermittent
DTC281D -Alternator serial interface
-Intermittent
DTC2747 - Misfire cyl 4
-Intermittent
DTC2892 -Misfiring
-Intermittent
DTC2742 -Misfire cyl 1
-Intermittent
DTC2743 -Misfire cyl 5
-Intermittent
DTC274E -Misfire on more than one cylinder
-Intermittent

The guy I spoke to at the garage said it could be one of those sensors at the top of the list which could be causing the rest of the problems and advised that I start there. Does this sound right to you? If I was to start at the Thermostat at the top of the list would this be the correct part to get first? http://www.ebay.co.uk/itm/BMW-Z4-E85-3-0-i-2003-02-M54-B30-306S3-170kW-THERMOSTAT-/272005638986?fits=Model%3AZ4&hash=item3f54ccab4a:grsAAOSw0HVWEPBS

What would you try first? Anyone got any advice?

Thank you.

Im gonna guess at CCV or split air inlet pipe...

did you check the plugs and coils ?

Coil pack would be my hunch too.

Another vote for coil. Just replaced 2 of mine with Bosch units as I had misfiring on cylinders 1 and 2 causing hunting idle, engine stumbling and hesitation.
