2001 Cadillac Catera 90000 miles

The car came in to my shop with an engine miss. Found spark plug boots contaminated with oil. Replaced valve cover gaskets, both coils and spark plugs. Now engine misses on all cylinders for first 5 minutes when engine is cold. Smoked intake and found no problem. Car runs fine after initial start and warm up. Thanks for help

Have you seen any issues with fuel in your area? In the past I have seen some of these cateras that have sticking valves due to a possible fuel additives getting on the stem. Cleaning the injectors with some top engine cleaner had resolved it. This was a cold only problem.
