It might be that either the Fuel Pressure Regulator (FPR) is bad and allowing the pressure to the injectors to be too high or the NTC (Negative Temperature Coefficient) sensor is giving a faulty reading to the ECU, making it think that the temperature is too low.
When things are working corrctly, the throttle position sensor wouldn't make the ECU put too much gas into the system.
Check these things:
1. Is the vacuum hose to the FPR on and does it have any vacuum leaks? Replace if necessary.
2. If you apply vacuum to the FPR, do you get gasoline out of the hose? Replace as necessary.
3. How new are the plugs, wires, cap, and rotor? If the plug gap is too large, it won't start easily. Same with the condition of the cap and rotor.
Check the easy stuff (the things above) first. IF they don't pan out, post again with your findings and we'll go from there.
