I had a rough starting when cold issue. Checked the codes and discovered two codes for a lean condition in both banks. After not finding a vac leak, I replaced the MAF with a remanufactured one. After replacing it, the truck started up when cold and the two codes went away. Now I have a PO-102 code. (Low voltage MAF) I checked for leaks around the sensor and along the ducted, and the wiring, no issues found. Could the new sensor be bad?
