I don't know which Gov agency controls the rules of radio suppression, [ Maybe FCC or another enviroment control sorts],
but I can remember when Mopeds were first imported into the
States, they could not be Registered/ Inspected until a radio supressor/resistor was added to the plug wire end as it was not
a stock item.
So , I think there is some control on this . It may even be considered under emissions rules ???
I notice the 104 eng uses 2K.

I will do some homework on it.....

NON "R" plugs

Hello Arthur and Gilly,

Actually it is easy for me to get the non "R" plugs here in the Netherlands. They are still the standard plugs used by the Benz shop. I just stumbled on the R ones ( the ytriums) by acident. They were marketed by Bosch as the new standard on Mercedes etc. and I figured why not try them?

Well, I went back to the non "R" ones and am happy as ever to be driving a benz that does not stall or hick up.

The only thing missing is a 500E in my garage. The 300E 2.8 is a nice car but misses the kick of the 500E.
So who knows, maybe the next messages will be on a whole string of problems and frustration of the next project.

Thanks anyway and greetings,

My point being you are less likely to get a non-resistor plug "by mistake" for a car which requires resistor plugs as opposed to being given resistor plugs for an MB, which happens quite often when trying out an "exotic" spark plug.

resistor plugs

Hello Gilly,

I stand very much corrected. I have been driving the non resistors now for a while and the engine does react much better.

Once over 2000rpmīs she pikcks up better and the overall performance is smoother. A little scare when the engine would again start to cut out. I changed the sparks back to the much newer coper ytriums to see if the nomn resistors where aging. Then engine showed the same error so i put back in the on resistors again.
The cutting out at idle remains as before.
Only in Idle and odly enough it happened the first time when going from D to R to back up into a parking place. Since then she does it regularly, mostly when nice and warm. More in D then in N but also there I have to keep the engine running by keeping the car at revs over the limitt of idle. No warning lights nothing.
It may be a coincidence but since short I can hear a distinct airbubble in the warm heater air. As soon as I put the heating on I can hear water running with airbubbles trappped in the system.
Could there be a conection. I know there is an article about this in here but I can not find it anymore. Any thoughts or tips here.

I am pretty sure that my irratic idle mess has been solved. I originally did not mention that I had problems with my belt tensioner. Just 2 weeks ago I put in a new one and had the temperature sensor replaced as well(fan wasn't working). Now the idle revs normal. Every once in a while it surges slightly then normal again. Just a few days after I had the tensioner installed it started making noises again and the rough idle surging Reoccured in drive and park. So I brought the car back to my mechanic and he made a few adjustments to the tensioner and since then (about 10 days) its been fine without the crazy surges. I really hope this is it!!

So if you dont hear from Then all is well....and thanks everyone.

idle and stalling.

Hello Ron,

My staling problem is also finally fixed. After two air mas sensors my shop finally decided to check the wires from the sensor to the ecu, and behold,...big surprise, the wire was broken. They taped it up and problem solved. Iīm a happy Benz motoring guy again.

have fun,

i had the wiring harness replaced, then i believe another problem occured: the engine stalls when hot on decelleration for the first few hundred feet. what do you mean by relearning throttle stop and how is it done?? besides one stall when moving out of a parking lot engine idles and runs very smooth.btw it is winter here so problem is subsiding.(could it be a temerature sensor and which one???)
thx and happy new year
