Hi,

It's been a long time since my last post, I still have the Mb 190e with a 2.6 engine.

Last winter was a mild one -14C° at the coolest so the Mb never stall.

This winter it is different story, we already have some -20C° on a few morning.

Yesterday it was -17C°, so I drive wifey to work... The car stall at the exact same convenience store as usual.

Wifey just get out of the whitout a word and walk the 150 meters to there work place , leaving me with a stalled car.

I get a coffee at the convenience store and wait about 20 minutes.

Get in the car, put the throttle to the floor, crank the engine, after 15 to 20 seconde the engine start. I notice I'm a little bit low on fuel, a quarter tank.

I get to the pump to fill the car, when I open the gaz cap I hear a big Woosh. This start me to think this not normal...

I get back home and pull out my old Mb shop manual to find out that the maximun vacuum on my gaz tank should be 1-16 mbar and the pressure should not exceed 30-50 mbar. A milibar is 14.5psi divided by 1000, to make short, nothing that you might hear or feel when you open your gaz cap.

This morning it was -20C°, before she leave I open the gaz cap and let him loose so the air could go in the tank.

Success , the mb never stall and wifey was smilling at me when she get out of the car.

I will test all the parts for the evaporative emission system and report to you the one that was in trouble.

I' m just curious how many of you guys with a SSS car have pressure or vacuum in your gaz tank???

Easy to test just open your gaz cap after you make a ride with the car if you hear a Woosh, you a problem with your evaporative emission system.

Take care

Max
