[W126 Coupe] Burning smell and rough idling

[Rattie S]

Hello,

I posted a message about a month ago about some problems that I've been 
having with my car. 2 months ago, I had the ignition module and coil changed 
after the car died. It ran just fine for some time after that. About a month 
ago, I had two instances on one day when the car wouldn't start. It has been 
starting just fine after that. Some of you had suggested that it could be a 
problem with a fuel pump soldier point.

Recently, I'm noticing a burning smell when the car is running. The idling 
has been a little rough as well. I had stopped to pick up some food from a 
steert cart here in New York. I was a little suprised when the food vendor 
came out of cart and told me to have my "relays" checked out.

Any words of wisdom from the experts?

Thanks and best regards,

Itrat
