The shudder is not new and is generally related to the converter locking up too quickly after tip-in. That is easily remedied.

I suppose the unstable idle could be related to a lean condition, although it is quite uncommon to see lean conditions at idle. It may also come from too much timing at idle. Try adjusting the custom option for timing back about 2 degrees (-2 degrees) and see if that resolves the unstable idle. If so, we can fix that and the shudder at the same time.

Thanks.
