A P0172 SOHC mystery
Hello, everyone. I'm new here, wondering if you can help me out with some truck troubles. I have a 2005 4x4 manual Ranger with the 4.0 V6 SOHC (166K miles). It seems to run all right but has had a P0172 code for the longest time. OBDII data shows that the long term fuel trim is extremely rich...- Alligator Wrangler
