I have an issue where my Cruze will reduce the throttle when trying to accelerate. Sometimes it will cut back to about 25% but isn't always as drastic. I could see if it was spinning the tires but it isn't. It will do this ]even on the expressway. The knock retard when it does this is typically only a couple of degrees max when this takes place. It also shouldn't be trying to reduce torque because those values have been increased. I am at a loss why this is taking place.
