The very first thing to do when you experience power loss or surging issues, or interesting gauge readings, is have your vehicle scanned for diagnostic troubleshooting codes. Your car can set these codes and not always illuminate the Check Engine Light. So always try to scan your vehicle right away. You will want to look into cleaning some part of the engine. Look into removing the EGR valve and cleaning it well. You may also have a bad sensor, and this is another reason to scan the vehicle. I suspect the ICP (ignition control pressure) sensor. Other abstract issues may be poor oil quality or a turbo issue. But these are less likely. Have a certified professional diagnose your RPM concern in person so that this can be addressed.
