Rough Starts for E420; Injectors Cleaned, etc., - now what???

When first starting the car in the morning, it feels like somebody is doing jumping-jacks on the front of car. This lasts for around 30 to 60 seconds.

When starting the car after it has been sitting for awhile it is not a smooth start (not nearly as bad as the firsm morning start, but still not good). It kicks over, feels like a big miss and then kicks over again.

The injectors were removed, cleaned and had the following items replaced - pintle caps, filter baskets, o-ring seal top & bottom. Before having the injectors removed, the jumping-jack problem was once every couple of weeks and there was no problem with restarts.

Also, the wiring harness has been replaced. Additives have been tried (Techron, Heat (for removing water) & octane booster). No difference.

Needless to say, the car is headed back to the shop. Assuming the injectors check out okay - what else could the problem be???
