Stangguy93 Posted January 21, 2020 Report Share Posted January 21, 2020 Hello All, I am new to this forum and am seeking your help to diagnose this P0301 code. I drive a 2007 Ford Edge and a few weeks ago my wife put E15 into the car accidentally. This in turn lead to my O2 Sensors reading lean in bank on and the P0301 code. I replaced the O2 sensors for bank 1 which got rid of the bank 1 lean code but the P0301 code continues to plague me. I changed the spark plug but still no change. My next step is changing the coil and the fuel injector, but I wanted to run this by you guys to see if there is anything I may be over looking. Any help would be greatly appreciated!!! Thanks, Mike.

orangeedge Posted September 27, 2020 Report Share Posted September 27, 2020 Did you get anywhere with this? I am having a cylinder 1 misfire and put in new plugs and swapped the coils front to back and still getting a #1 misfire. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 28, 2020 Report Share Posted September 28, 2020 have you checked codes? that is a necessary first step. could be a failing injector. Year and miles? Quote Link to comment Share on other sites More sharing options...
