My 2006 F250 6.0 while driving will sometimes show "0" RPMs at Idle then maybe 1000 WOT.. But the truck is fine drives fine I see no issue other than the RPM on the dash drops.. Only codes are from the EGR delete and P1000 or whatever it is for the onboard system readiness check not complete or something.. Any ideas? If I shut the truck off the RPM gauge seems to be fine.. Thanks!
