380SL Help...runs barely

[jim blanton]

Good all,

We bought a Nov 80 380SL a few months ago and have been
working on it ....first it was one lifter...replaced that...then plug wires,
roter and cap...new plugs....new vaccum lines and connectors...new
fuel pump...new filter...fuel resv...and lines that hook the fuel systen
together..and the filter in the tank...

At that point it ran but had the high idle pb...new control unit and
now the idle is 750 more or less...

Now the real pb....the thing starts fine...idles fine...until you
get up 1300/1400 rpm...starts missing....vaccum gauge starts
to the left...if you let it drop back it runs...if you try to give it more
gas it dies.

Checked the fuel press and its abt 5 bar...steady...

Anyone know what is going on with this car....
