Cold crank
Outside temp. 0 degree celcius.
M112 60,000km. Brand new battery.
AVR testing performed today. Alternator and battery reads good charging voltage. P0131 came on once then cleared. Car drives fine as new. idleing is fine.
BUT CAR STUMBLES ON COLD CRANK FOR 30 SEC THEN STALLS. It barely cranks in about five more prompts. It cranks just fine when weather is nice. PleAse help.

MB 100 ah battery?
What do you mean by "cranks"? Crankshaft turns over? Motor starts? By "stumbles" do you mean motor starts but misses and eventually stops?

P0131 = O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1)
Do you have the correct 100Ah battery?
As with the temp sensor I mentioned in the other thread. If your upstream O2 sensors are getting old and cycling too slowly the direct result is engine stumble because your fuel trim is wrong.
