There's a whole bunch of posts in here so far assuming the guy has no idea how to drive a stickshift. Yeah the car makes like 6hp at idle but it's also a featherweight. I have yet to stall this car.
Besides he's stated several times that it chokes out at initial throttle input.
You are running incredibly rich by the sounds of it, whether by program (sensors) or by fault (improper combustion).
What fuel economy are you currently getting?
How long have you had the car for?
Has the fuel mileage become worse over time/since this problem started?
They all have tachometers don't they? What rpm is it idling at?
Does it feel down on power full throttle once rolling?
When was your last oil change? Air filter? General tune up?
What other issues showed up around the same time as this problem?
Was this sudden or a slow onset?
And finally, do you actually know how to drive stickshift?
