My truck is a 93 7.3 E4od 4x4. I had a problem with delayed late and hard shift with heavy pedal. Idle voltage on middle wire was 1.230. So i lowered it to 1.03x and it shifted a lot better. Drove it around for 2 days and then flashing od light came on. Turns off with key and comes back on after i hit 45mph. So i thought I had maybe adjusted it too low so I bumped it up 1.1xx and it still came on. Disconnected battery's for 10 min , plugged it and shifted fine and od light didn't come back on but full throttle shifted weird and was like gear hinting 3-4. Checked voltage through sweep and WOT is only at 3.6. I was told min should be 3.8. Bad tps?
