Does that mean you were a former Channel Islander, Ivanerrol? (tell me you weren't a crapaud  !!) - sounds like I have the same model car as you feature-wise (or lack of features).
I read elsewhere that your present home country and other parts of the world have low octane petrol such as those you mention. In the UK and CI you cannot get lower then 95 at the pump and 97 is available as 'Super Unleaded'. The EZL is set as appropriate for 95 RON.
I twiddled the idle adjustment and now it sounds like its almost going to stall when stopped in gear - not a simple thing to play with, clearly... will have to tweak that back to normal now.
The air temperature recently has been around 5.0-6.5C according to the dash readout and I have noticed the engine temperature has not gone much above 40C and from reading other posts on this site the engine should be at 87C under normal conditions. I suspect the usual cheap-o-mechanic job of not fitting one when the water pump was replaced, if not simply rusted 'open'. Some replies to those posts suggest that fuel economy will suffer as a result of the temperature sensor not detecting a warm enough engine to switch off the cold-start injectors, etc. As this should be cheap to replace I will venture down this route next. Might driving with 'choke' effectively on impact on performance?
As a general question on coils do they really become 'weaker'? I would have thought they either work or fail. I am happy to replace the coil if someone can confirm that changing a coil gives a definite improvement?
Many thanks,

Not from the channel Islands - Cheltenham and Edgware- many many moons ago (with wet nappis on).
The car I bought was imported to Australia as an export model from the U.K. via Singapore. Technically this car should not be allowed on our roads as there is no cat fitted. In Australia we have 91,95 and 98 Octane. Leaded is now outlawed. The EZL switch can be adjusted to let the car run on the lower 91 Octane , However the 98 Octane has additives that "clean" injectors and fuel injection components. It's always better to run the car on the better petrol for this reason. Anecdotal evidence from Benz mechanics here have confirmed that cars run on 98 Octane have "cleaner components" than those which are run on lower octanes.
Coils can slowly deteriorate and the heat affects them. They are positioned in an area that can catch the heat from the radiator. Replacement is a good option. If the electrical system - plugs, leads, dissy and coil are not in good shape then the car can never be tuned properly.
The thermostats are cheap and easy to replace.The car should have the 87 degree one as OEM'd by Benz.
You car will not go over 40 degreesC. Last week we had 40 degreesC as an ambient temperature.(in the shade).
