84 380 SE - High fuel consumption and not the best warm start
Here are some symptoms in my '84 380 SE:
1) High fuel consumption
2) Starts at the flick of a switch in the morning. But when warm, it takes a couple of turns of the engine - not terribly bad though.
3) Once in a while, when warm, if I let go of the ignition immediately when starting, it seems that the car wont start but then it kind of "catches up" and starts
4) If I am trying to warm up the engine at 1000 rpm or so, it seems I loose control over the revs and it varies / hunts from 2000 rpm to around 700 rpm. This does not happen always. Normal idling is at 500 rpm.
I really want to ensure that the car does not use any extra fuel. I am willing to sacrifice performance if I can somehow throttle down the fuel consumption.
Any advise on what I should do is greately appreciated.
