Hey quick question, when I tend to take off, my Monte tends to give a hard "skrrt" and jerk. Like a mini burnout, you can even hear about a 2 second tire screech. Keep in mind my check engine light is on with the cat code. Could it be my cat or something else? Also when I make a sharp left turn it tends to loose power and does the hard takeoff again. What could this be, I'm lost, thanks!!
