I have a Holden rodeo v6 2005 auto and it keeps reving high and low when lam diving has anyone have any idea.

Hi Jim I see someone else has requested more information i am unable to find your reply. When does it rev high and low? if it is when the vehicle is stationary ie stoped at lights at idle. Bare with me i had one with the same fault, it took a while to sus it out simply because of what was causing the fault and would not have found it without connecting Tech2 (diagnostic tool) this gave me the information required to locate the fault. now it may not be the fault but it may be worth checking A shot in the dark !! Check the power steering switch from memory left side (passenger side) down low of engine just able to be accessed. check for a high resistance ie poor connection /dirty connection / pinched or damaged wire. If this does not work would advise Holden dealer a Diagnostic scan should be carried out. Good luck
