Is the W126 500 SEC idle problem solved?
I recently bought a 500 SEC which is lovely and very loved (full and mostly MB history) However it’s got a niggle… at idle it will occasionally cut out, always restarts fine and is fine when off idle. Sometimes it will be fine all week and then do the “death at idle” thing twice in the same day.
Why does my car not run at idle?
Mileage should not have anything to do with idle , especially if the problem is intermittent. A small vacuum leak will create a high idle issue , a big one will result in it not wanting to run at all. Check the vacuum distribution hoses that run on the inside of the cam covers.
Why does my Mercedes W126 idle at low speed?
Check the vacuum distribution hoses that run on the inside of the cam covers. Because you don’t run your car often, your fuel system may be gumming up. The fuel pressure to the injector is driven by the fuel distributor and metering device. If you’re not getting adequate pressure to the injectors , it will run poorly at low speed.
