Hello all, I have been narrowing down an intermittent fault I keep having. Deduced the
spark plugs, coil packs are not the issue along with the battery and alternator as potential problems. It started a couple weeks ago, when we were coming back from a beach trip and the LX just died when coming down over a pass ( low elevation). Went through the troubleshooting process and after running fuel trims (see below) looking for more help from the collective group. I just cleaned the MAF, but I'm thinking after 260K miles the fuel pump might be giving up the ghost. The Torque screen shot is during minimal throttle and the attached fuel trim csv is covering bank 1&2 short term and long term fuel trims. Looking for any insight or further tshooting before I bite the bullet on a new fuel pump. Of note, my first thought is the long term looks a little off. Thanks.
