Throttle Position Correlation?

I have a 2003 Dodge Neon SE and I am getting a Throttle Position Correlation code... I just replaced the TPS, so I dont think it is that... It also says above the code, MAP/MAF, so I am guessing it is like the MAP sensor or something... Any incite would help... When I turn the car on, it instantly sky rockets... Just Revving all the way up! Then when you drive it and let out of the clutch, it will run Ok, but won't idle right. Just keeps have a very deep stutter within the revving... Then it backfires...
