My 2011 chevy cruze started jumping and sputtering on full acceleration or whenever it's goes above 15 psi. It started doing this a few weeks ago and thought it was the ignition coil. I changed the ignition coil and it was fine until about a week later when it started doing it again. On full acceleration the traction control and stability control will turn on sayings it's failing or something like that and the engine light will blink. As soon as I let off the accelerator it all goes away. I am tuned and have a down pipe and CAI. I would appreciate any help that you guys can offer thanks.
