All
just bought a 92 w124 230 te, the idle is rough, the engine will rev to 1100 rpm and hold then drop to almost a stall then back to 1100 rpm.
If I blip the throttle to 3000rpm and release the revs drop but hold at 2000, 1500 rpm etc then down to a steady idel.
If I select D the revs drop slightly down to 500-600 rpm.
Ive cleaned the idle control valve, replaced the plug also as the wires where exposed.
Disconnected the cold start valve no change.
checked all breathers and vac pipes all good.
Any other thoughts please.
