I don't know what year you have....but check the wiring leading to your PCM, passenger side goint into the firewall. Is the insulation cracking or flaking off. Look at the rest of the wiring under the hood is the insulation flaking or cracking...I had a devil of a time with my car starting and then dieing out, sometimes would start fine other times it seemed like a different car. went ahead and removed intake manifolds for cleaning, etc. and found that the insulation to my injectors was completly gone. Also the insulation going to the pcm at the firewall was also flaking and or gone. When I pinched the wires at the wires leading into the firwall the car started perfectly and ran fine. Had the wiring replaced under warranty.
