I just received my Dhp PCM that I bought offline. I plugged it in an turned the car over and it started and idled for like 1 second then shut down and would not start after that. My gas milage reading in the DIC was flashing and my traction control light off was illuminated. I unplugged my battery and let sit for 20 min and tied again and it did the same thing. Any suggestions? Send it back? Thanks!
