P141-O2 Heater...
Clearly the last 2 are because I dont have the rear O2 sensor pluged in and the first one is because I did the 6Bolt swap. But what is the 2nd one? Fuel. Could that be why my car shakes. Now that I think about it it could be lack of fuel. Everything in the fuel area is stock and I just replaced the Filter like in september. The only thing not stock on the fuel is that I caped off the line that goes to the emisions(gas tank vent). I have it still pluged into the soleniod(vac lines).

The fuel trim error is because you are running too lean or too rich at in closed loop. If you get more than 12% too rich or lean during closed loop, the ECU throws that error. The random misfire error can cause problems with how the cars runs. You should get DSMLink on it to get rid of the random misfire error and help you tune it correctly to avoid the fuel trim error.
