6.0 no power!!!!
Hello all, this is an amazing & informational site.
I have an 03 f350 with 6.0 with no take off Power, but in third gear it finally gets up to speed. I had a guy change turbo, icp sensor & air cooler. I then took over & found contribution test to be low on #2 . I tested ficm & found 48volt with key on but when started engine it dropped to 24volts. I had a used one on hand that came off an 05. It had 48volts when running & contribution test then had all cylinders @ 0%. It ran a little better, but still no take off power. I then took to dealer to program ficm to PCM. But problem is still there. They told me to rePlace icp sensor.. But as I stated it is new... I performed buzz test, & had no codes. Any ideas???
Thank you.....
