of issues after a few tanks. but mostly its time to get a second opinion.

Thank you for you respone. This was the second tech that I have been to. The first one charged me $300 to replace a distributor cap and rotor and suggested that I confirm that all the fundamentals were working first before going forward.
I was recommended to go to this second tech who had 15 years of experience with MBs and Audis. My 300E was imported from overseas and has only 31,000 miles and was not driven very much at all. The mechanic identified that there was a pressure leak in the fuel system which would account for the difficulty in the cold starts in the morning. He indicated that the air had to be displaced in the system before the gas could reach the engine which would account for the difficulty starting. He also removed one of the injectors and confirmed that the spay pattern of the injector was very irregular and was caused by residue in the engine and the injectors. This was preventing the injectors from closing properly and allowing a leak of pressure.
Are these accurate conclusions. From my limited knowledge, it would seem to be reasonably accurate based on the starting issues I am encountering..
