Having the issue where my 2007 Jeep Wrangler Jk with the 3.8l V6, will throw the ETC (electronic throttle control) light and the ESP (electronic stability system) on the dash dropping the rpms then raising them back to about 1100 rpm at idle. Sometimes it’ll kill the engine the idle is so rough, it threw the code P0507 (attached picture). I’ve already went down the rabbit hole replacing the spark plugs and wires, coil pack, battery, throttle body, PCV valve, camshaft position sensor, and the crankshaft position sensor. I’ve got no vacuum leaks and the grounds are all nice and snug. Happens while idling whether it be in Park, Drive, or Neutral. Most forums I read show that people have this problem but they never show the solution. I’ve wasted so much time and money on this issue already! So if anyone knows what this could be please LMK! Thanks

Code P0507 (Idle air control system RPM higher than expected.)
