MAJORLY running rich

[yekrahs]

Okay I was driving my car on the freeway and I shifted into neutral to take an exit and right before I put in in N I saw the rpms drop. So I coasted to the stop sign not thinking anything of it and when I tried to go all I saw was black and white puffs of smoke and my car was bogging. Now I have a b16g, 550s, safc, fmic, stock fuel pump, etc....I have tried adjusting my safc and it has no effect it runs exactly the same. I have tried everything I can think of. Boost leak tested, new plugs, wires, the fuel filter is brand new so is the fuel pump, the injectors are brand new, new stock fpr. The only thing on my list is maybe the o2 sensor. I threw a CEL and it came up with:

P1104:
Turbo Charger Wastegate
P1105 Fuel pressure solenoid malfunction
P0115:
Engine Colant Temperature CIrcuit

I have an external wastegate, I replaced the fpr, and I'm not sure about the coolant tempterature circuit, but it doesn't have anything to do with this more than likely....any ideas?

A failing coolant temp circuit will make the car run rich as a result of the ECU never seeing full warm up. Typically a warm up cycle is more rich than standard operating temp and as such, if you're dumping more fuel on top of an already air/fuel ratio, bogging, spitting, smoking and major performance will be the result.

Just for reference, I've inlcuded a pic of the sensor location from another thread. Replace it and get back to us.
