Hi Ken, The compression is pretty good.. Typically you want the lowest value to be within 10% of the others - which you are.
Is it possible the IP timing changed? Does it do this when warm or only when cold? My 91 300D 2.5T did something similar - but it was intermittant. It would smoke heavily (white smoke) , have no power and then gradually get better as it went putt-putt down the street (very embarassing), I believe it was caused by heavy carbon builld-up because of the POs driving pattern which was 5-10 mi /day for 13 years - in New England where there were many cold days so I'm sure the engine never warmed up. I'm sure it was carbon buildup and I used some stuff called Ferox (3 bottles) for about 6 months. My wife also drove it 100 mi round trip to work daily at 65mpf which went a long way to clearing all problems. It cleared up and hasn't happened for the last 18 months. That's my guess - but your compression is very good.
