on my 1984 190e 2.3l there are two relays behind the battery. I know one is the load reduction relay that controls the k-jettronic and the idle stabalizer, but what does the other small relay control? the problem I am chasing is a rich fuel mixture. By unplugging the eha valve I can get it to run until it warms up and the plug in the eha while running if the coolant sensor is unplugged, then reconnect coolant sensor, runs good after that. Now back to the question, It did stall while idling a few times, when it did the relay behind the battery was clicking, when I moved it around it stopped (like a poor connection). this car has sat for a few years and the more i run it the more things start working( like the windows, clutch fan, ect.) any help would be greatly helpful. I am an ase mechanic with many years on audi but am still learning on the benz. I want to start driving this car soon. thanks again.
