...it has no power. EGR Valve? As I drive down the road I seem to be pushing on the accelerator more and not getting any where. I was told it could be a EGR Valve or Oxygen sensor. What is a EGR valve? When I try to start the Jeep, I have to keep my foot on the gas and then put it into drive quickly or it will shut off. Any help would be greatly appreciated. Thanks...
