High Low Rev at start 1972 280se 4.5
I have learned that pictures lie and believe none of what you read!
Last May I bought the "Rags to Riches" MB on ebay. I drove it til November when it wasn't in the shop. It is now back on the road for another summer of tweaking. I have replaced lots of stuff, starter, steering linkage, fuel pump, major tune up etc, and more to come.
My issue is when I start it to warm it up, it revs really high, drops down low, revs high and so on. Then suddenly it's fine. If I put it in drive it does not happen. Since I have a driveway between my neighbor and I, the noise can be an issue at 7am.
The other question would be my idle, too high and the car bolts when put in Drive, too low and it stalls.
I have a very nice inexpensive local mechanic I like, but it's new to him too.
