Re: Please help!! My wk is acting up
Likely your throttle postion sensor (is everyone getting as tired of seeing this typed as I am of typing it?). VERY common on the 4.7l. To know if it is the very least contributing to the problem start the car, pop the hood, grab the Throttle Position Sensor between 2 fingers at the connector (still connected) and jiggle around. Its obviously not going to move as its mounted firmly you just want to apply pressure in different directions. If your idle speed goes crazy AS you do this then replace the TPS.
