so my 05 cobalt ss just isn't running the same sometimes i get lean codes sometimes i get random check engine lights and they go away after a while, but car just doesn't feel the same anymore it feels like its being held back. can anyone help me out with a tune or a re flash anything helps feel free to text or call me prefer text first 813 454 8712

 

something is proably wrong with your car not the tune. fix the issue...don't try and tune it out

 

alot of people have been saying its the ecu tho like the car idles at 1500 until i come to a complete stop.
