ok, i just bought this truck in texas on sat, drove it 40 miles, sel light came on, lost power, pulled over let sit, restarted, drove for a while samething, driving from texas to mn, finally bought a code reader in missouri, p0038 code. i was able to clear the code as it came on to keep driving it home.
the truck has an 4" exhaust, and a bully dog intake, probably a chip at some point, got from dealer. where is the o2 sensor suppose to be? any fixes? will a bully dog programmer fix it?
thanks from a 6.5l owner to a DURAMAX owner. yea!!
