Hi! I'm having issues with my 3.0 v6.
When you start the car in the morning it starts almost immediately, like it surges a little before starting, then it's a little stable like 10 seconds, after that it starts running like crap, idle fluctuates, engine misfires (not constantly but randomly), after it warms up and the idle goes lower I can feel the engine wanting to die, for example if I'm in Drive when it's misfiring it wants to go forward while the brake is pressed but randomly, half a second it wants to, then it doesn't... etc. I have to mention that in all times the exhaust smells strange (not precisely like fuel smell when you are cranking a car without spark, but a more different and annoying smell) If I press the gas a bit it stabilizes but after releasing it goes back to doing the same thing. Car has ok power when accelerating(better on hot, on cold it feels heavy). I don't think is having a lean misfire because I don't get backfires through the air intake and I don't think a lean misfire would make my exhaust smell funny, on the other side it backfires through on the exhaust, while it's misfiring. KOEO and KOER says 0 codes, but only one for the DPFE (which is broken so no surprise). Compression doing a CF crank sounds very even. No vacuum leaks. I thought about pip sensor but disconnecting the spout makes no difference, I have new cap and rotor. Could it be the TFI?

Your smell could be due to partially blocked cats or exhaust which will also cause engine problems .If not that an overcharging alternator can cause " smell " also . You may have other faults apart from these , but many possible other causes .

There's no cat in here, I removed it 5 months ago, the alternator is charging to 14.1 volts

You're pretty much correct, forgot about the generation of OBD.
