I have just redone my 1982 240D sedan and updated/replaced most everything in the engine (other than the actual engine). I had noticed that the altitude adjustment doodad on the top of the engine HAD been disconnected for some time. We reconnected this unit so that it is NOW operational. I have noticed a marked reduction in the umph factor of the engine when starting off in first and second gears....very sluggish....and am wondering if the alititude adjustment unit is contributing to the lack of any pep in my engine?

It might also be that we have installed a brand new A/C compressor on the car (not operating for about a dozen years) and this is drawing on the engine and causing slow, sluggish pick up from a standing stop....don't know....

But we're a bit surprised that the engine is this sluggish when starting to move the car up the speedometer.....any ideas???? Thanks.

 

We'll have to undo THAT improvement immediately...thanks for the heads up.....
