I've been working on my dad's 190e 2.3 which is the only car that I am allowed to drive. So, I kinda need it to run. Anyway it doesn't start consistantly and runs rough until it warms up. My dad found an unconected vacuum hose and we haven't figured out where it goes. The hose is one of the three connected to a thermal switch on the right-front side of the engine. My dad plugged the hose, but the car still doesn't start. He thinks that the vacuum connection is important for the car to start. Either way, I can't find a schematic for the vacuum system anywhere so I don't know where the hose goes. If anyone could share any information/schematics with me I would really apreciate it. Also, if anyone has any other explanations for the starting porblems I would apreciate that as well.
