To start out, the other day I plugged her in (engine block heater) for eight hours as a test, then started her up when the temp was around 25 F. Instantly fired up, fast idle kicked in and went to about 2,500 RPM. Was as close to "running like a dream" as you can get.
Any other time, when she isn't plugged in and the temps drop, I give her two gas pedals to the floor, start her up. She'll start up but start bogging and choking right away, and will die unless I give her gas to manually rev her up to 2k RPM. All the while thick clouds of gray/black gas smoke is pouring out the back, strong gas smells all around. If you sit for a bit gas actually starts dripping out the tailpipe! If I try idling her at this point she bounces around 1K RPM. The fast idle doesn't kick in until a minute or two after she starts.
If you try driving while she's like this, say, put her in reverse within 30 seconds of a cold start, she dies, and won't restart unless wide open throttle is applied, and even then I have to nurse her to start.
If she is plugged in first, or at operating temperature, she starts, runs and idles fine.
I plan on getting some videos to give y'all a better idea of what's going on, but until then, any ideas?
