Ok guys I got a 2014 coyote thats swapped into a 66 bronco all of a sudden its throwing p315 ckp variation not learned there is no other codes and runs fine until its driven and has a load then goes into limp mode and 315 returns but it will come right out of limp for a few and go back and fourth seems that tps gets cut can rev in park no issue. And on to my next issue im was gonna try and turn code off but when i went to pull file its seems to be locked whats my next step?
Can i flash a stock file over it? I have access to forscan. Thanks in advance
