C1278 TCS Temporarily Inhibited By PCM
 

Would this make the car run badly? I just went through the grounds and they are all good, so I checked the DIC and it threw two codes: this one and the vertical seat position sensor is bad. If the PCM is controlling the traction control system, how do I wrest it away from her (assuming controlling feminine gender from past history)?

As it turns out, all the goofy codes go away once you replace a broken valve spring. All better now.
