Mysterious Cold Weather Stall...
Some quick stats; car is bone stock, low kilometers, runs fine, newer air cleaner, new plugs, and, yes, throttle body cleaned out (I cleaned the living fook right out of it and then some whereas it was actually quite clean to begin with). The car is auto shift.
The spontaneous mystery stall only happens when it's both cold outside and when I don't let the car fully warm up before I drive it. It mainly stalls when when I back out of my stall in at home or at work or wherever. However, I restart and all is reasonably well until the car reaches normal operating temperature.
...It's only a cold stall and not a shudder stall like from a malfunctioning TTC solenoid (had a '92 Z24 that had that issue and it was quite scary how it would fricking thud, bang, and shudder when stopping for a red light/sign).
...The car runs fines when it's either cold or warm, no misfiring or any other wonky things other than that cold engine stall.
...I managed to catch a view of the RPM jumping up a tad and then quickly falter into the stall.
Any leads from the vast collective knowledge base of the Cobalt/G5 nation? I'm at my wits end on this one. Thanks for reading. Let me know if I missed some details or if I could provide you with more details, but I think I have all the main areas covered, per se.
