P0171, P0300 and Stabilitrak
I have a 2007 GMC Sierra SLE 5.3 L 4WD that has had a P0171 and P0300 plus Stabilitrak off and Transaction Control off thats comes on. When my P0171 and P0300 throws, the stabilitrak and transaction control always comes on. I do have every once and awhile service both stabilitrak and Transaction Control message. I have taken it to a few shops and they cant figure it out. I have replaced plugs and wires, bank 1 pre cat O2 sensor. I have had the MAF checked and they said it looks good. Every shop has checked for vacuum leaks with negative results. I have had my fuel pressure checked and they said it looks fine too. What else could it be and what am I missing. Thanks for the help.

Sorry for so many posts, I also had front end work, replaced the ball joints and u joints. Also had oil pressure send unit replaced and they took the intake off and replaced with new intake when they put everything back together.

MiguelTapiaa....There has been no progress with this issue. I can drive in 3rd all day long with no issues. When I put the truck in drive it will take a few minutes but the codes will throw. Have you had any progress with yours?

The dealership said the book said to take off the intake to replace the oil pressure sending unit which i knew you can get around and leave it on. I told the dealership to leave it on. But they didn't listen, then when i got the truck back it started to throw the codes. I will see about getting the injectors looked at. Would it still be an issue with running in 3rd?
