car was about to die in the middle of the intersection
 
On my way driving to the train station, I stopped at a traffic light to make a turn. I then realize that the car started vibrating slightly and that was due to rough rpm ( about 500rpm). The battery light then started flickering. If I haven't given the car gas during the intersection, the car probably would have stalled. Car seems fine at normal speed but when driving slow(5-20km per hour) this happens.
What could possibly be the problem?

Dirty o2 sensors?

Alternator

Alernator is a bosche brand and was replaced a year and a half ago.

Vacume leaks or alternator. Most othe problems will just cause a check engine, run in limp mode, but not actually stall.

Will I have a small evap light last time I checked. I'm not sure this problem could be.

Ok so I got my codes scanned and got P0442 and P1250.
P0442 is the small evap light my mechanic was talking about.
But what about P1250? Someone mentioned that P1250 was the fuel filter but what fuel filter cause my battery light to flicker when my car was about to die?

When car goes under normal idle (almost die) its normal for the battery light to come on (not charging enaugh)....Fuel filter can NOT have its own code, as it has no electronics to it, its just a physical part that separates dirt from gas! *wave*

Yes, i think the 1250 sounds familiar when i had to replace my MAF 2 years ago...
Or it was general missfire!

Hey guys i appreciate the help.
My peake tool finally arrived and I did a scan and came up with these codes:
80 : EWS Signal
91 : EVAP small leak detected
dE : Coolant temp too low for closed loop operation

The small evap leak is not new to me, but the EWS Signal and the "Coolant temp too low for closed loop operation" are things I have never heard of.
Any idea what could be the problem?
