Where is the idle control valve located in 1987 190E 2.3L 8V
 

Please help! Anyone know where is the idle control valve located? If you can, please post the picture. Thanks

If standing at front of car looking at engine, remove the air intake and it is just behind the fuel distributer. It has a black hose going into the top of it. And it sits in a black rubber holster nested between the intake manifold arms of cylinders 3&4.

It has two hoses going to it. One is underneath leading to the bottom of the air plate and the other goesd to the manifold.

Fastlane has a nice picture of the little trouble maker.

Idle control valve
 

I have a 1985 190e and recently replaced the dry rotted hoses on the idle control valve. My question is the hose on the bottom side that looks like kinda like a U had a metal pipe attached to it when I removed it. This pipe looked to be broken off but Im not sure. Does anyone know if this 3 to 4 inch metal pipe that connects to the bottom rubber hose on the idle control valve is supposed to be attached to the engine or does it just slide in a hole on the engine or something? I replaced all the lines but the idle is still high and I think its leaking at the metal pipe. Anyone that can help?

Hi! Today, I took off the air filter housing and used Lubro Moly Air Flow cleaner to clear up the idle control valve, air flow meter and an air pressure valve (beside the cold start valve). After that, I also find out the preious owner did not connect one air hose from engine to air filter housing. I put everything back and connected that hole back to air filter housing. I start the car and drive and 40 mins (city drive "stop and go")---- No stall and idle is around 850 in "P" or " N" first when engine cold. When shift into "R" or "D" becomes 800 (cold engine). After engine warmed up, the idel is about 800 in "P" or "N' and 750 in "D" or "R".

I hold that it will fix the stall problem.

One more time, I found that it has a connector plug from the main wire (beside the idle control valve). It doesn't connect anything. Anyone has an idea for??? Thanks

maybe r16 resistor? Thats in that area my 190. It is rectangular and has electrical tape wrapped around it.
