Ok. The p0068 indicates a problem between the throttle position sensor and the MAP sensor. Basically the computer is seeing that the two sensors aren't communicating with one another correctly. According to dodge, these are the possible causes:MAP sensor signal circuit is shorted to groundCheck for a large vacuum leakTP sensor signal circuit is shorted to groundMAP sensor ground, signal or reference voltage circuit has high resistanceTP sensor has failedCheck for a restriction in the Air Intake systemTP sensor ground, signal or reference voltage circuit has high resistanceMAP sensor has failedPCM has failed

I would probably check for air leaks first. Look for tears in the air ducting or mis-installed air filter. From there I would get a hold of a scan tool if possible and check the signal from the TP sensor. If that looks ok I would check the wiring to the TP sensor and the MAP sensor.
