The car is a 1990 190E and just received a 60k mile service. Today while I was at an intersection where I had to yield, my car stalled as I was inching forward. It totally surprised me as it had never done this before. Well, maybe once or twice in the past, but only when I start the car and it dies in P mode, but never in D mode. Anyhow, I started the car and it fired right up--normal as ever. This has never happened before. The car has always ran well. And after this major service it still runs well. I can't say that I notice any major difference after the service, but at least it still sounds and runs the same (i.e., GOOD). The stalling has not happened since that incident. The car runs great. Can someone tell me what happened and should I worry? Thanks.

Hi,

Same thing on my 300E.

Check the vacuum lines around the engine compartment. Especially the one near the starter. That's what caused my stalling problem. About $150 to replace it plus $75 for a diagnostic fee.

Good luck,

PS: Change your fuses now. Don't assume they are good by looking at them. And plan on replacing your relays over the next few months as a preventative measure.

Hello

Yes, my question is where, where are those vacuum lines?

I have the same problem (car stalling) and I already tried to have a look on those vacuum lines.

But there inside are alot of wires and lines and I can't define which line is what.

Can you give some advice to easily find out which line to check (color, position, picture, etc.)

I would appreciate your help.

Regards,

Hi,

For one thing, replace all the breather hoses connected to the Idle Control valve. Also the breather hoses from the valve cover and intake manifold.

As for the starter connection, I'll have to wait and see until I get the car back.

Should be in the serivce manual though.
