Hey Scotty, watch your youtube channel all the time. I own a 2000 Toyota Avalon with 189000 miles. Last week I got a P0420 engine code when driving. This week I'm getting a P0171 code along with the P0420 code. I took pictures of the values I found for the ST FTRM1 (and 2) and LT FTRM1 (and 2). Four pages of data were available. Any ideas what might be the problem?
