I have a 2005 Chevy Malibu 3.5L V6 that is displaying "engine power reduced" message for the second time. The engine light kicks on and traction control is forced off. The throttle becomes extremely weird when this happens. This is the second time of this happening. The first time, I warmed up the engine a little with a heat lamp and kerosene heater to melt any frozen moisture that might have caused something. Then I disconnected my battery, therefore, resetting the computer. I left it disconnected for about 30min and then reconnected the battery. It worked fine after that and ran 100% normal, but now it's doing it again. Not sure what to do next. Thanks for reading! All suggestions and ideas will be taken into consideration!!!
