OBD2 wont turn on!!!
My OBD2 fuse had blown, i think when i used the 12V for an air pump but when i put a new fuse in it was fine. The 12V still doesn't work so i have to check it out..can you disconnect the 12V somehow and just try the OBD2?- 2004DenaliXL

Power Loss, Bad Mpg, Weird Shifting
My 2004 Yukon Denali XL had sensors go bad, it was traction control, or wheel speed sensors. When pulling out from a stop sign or stoplight when you would accelerate it would bog the motor down and downshift sometimes. After I had the sensors replaced it was fine.- 2004DenaliXL
