Bad, bad, misfire when warm..
My C230 has developed a problem.. A quite strange problem I can’t seem to figure out. On cold start it’s great, runs great and smooth. But as it warms up the idle starts to get choppy. By the time it’s at operating temp it’s full on bouncy house in the cabin. If anybody could point me in the right direction it would be greatly appreciated! Thanks in advance! - Collin

Any CEL lit? If so, what's the code(s)?
I would look into the spark plugs and ignition coils. Something may be broken internally, with the gap increasing with engine temperature.

Yes, need codes. Misfires like that will definately trip the CEL.
Coils when they get old, are effected by heat for certain but this could be anything.
