2003 Explorer, 4.0 SOHC Flex, 58k. I have been working on my rough idle off and on for about a year. It recently worsened and is driving me crazy. I am not getting any codes and have replaced all the obvious sensors. I recently spent a few hundred on the front end and would really need to properly diagnose what's wrong instead of throwing money at the problem. I started pulling data from the ECM and believe an experienced person in reading it could diagnose this issue. I'm out of ideas and exhausted at this point. The link thread below has everything I have replaced or tested. Anyone seasoned in reading all of the sensor data?
