Rough idle with engine misfire and SES light on
 

When I start my X5 on cold mornings and after it's been sitting for few days, the engine idles very rough. The SES light comes on and sets misfires trouble codes 240 and 243. I shut the engine off and restart it after 30 seconds and the problem goes away. I am thinking the ignition coils need replacement. Anyone with similar problem ??? Any ideas ??? Thanks.
