hi, I have a 2003 dodge durango with the 4.7 and i am experiencing rough idling issues. When the vehicle is in park, it hesistates and sometimes shuts off. I don't know i this could be due to a faulty TPS or a throttle body cleaning is in order. Any insight would be greatlly appreciated.

 

idk how you are noticing hesitation when the vehicle is in park, but rough idle is one of a few things (in the order i would check them)

1.) dirty throttle body
2.) bad plugs (should be copper core champion plugs only)
3.) weak battery (replacement is the only fix)
4.) bad IAC motor
5.) bad tps
