Thanks for the reply. It is more than just a warm start problem though.
It will idle roughly until I shut down the engine. I have read on this
forum the warm start issues but many seem to clear after the
engine starts running. Once the engine starts in this mode it will
continue running like that.

I can shut the engine down and then restart right after and sometimes
the rough idle will go away.

When the engine starts are there parameters that are set, like
engine temp, outside temp, that may not be set correctly
and do not get updated while the engine is running?
