I recently purchased a 2006 chevy malibu ss with 45,000 miles on it. The past few days my check engine light came on and my car lost some serious horsepower along with hesitation to go. I took it to a chevy dealership who explained that the code was bank one fuel curve lean, and that all of my O2 sensors are working fine and that they wiped out the code and it's working fine. Um WHAT? Not too happy with that mechanic visit. What could be the problem with my car? When it happens it doesn't happen all the time, one day the light will be on, and one day it wont. It will also just come on when driving and my car will instantly start running like crap. Also my traction control keeps shutting itself off. Is that a speed sensor problem?
have the same problem?
