Asked by Aug 31, 2013 at 08:02 PM about the 2006 Chevrolet Cobalt LS

Question type: Maintenance & Repair

There is no service engine soon light on before this happens, i got to accelerate and it
goes to kick into overdrive starts to then falls on its face and says engine power reduced, i
have to unplug the battery for it to go back to normal. This happens about once a month, i
have changed plugs, air filter, etc, still doesnt throw any lights until it goes into engine
power reduced. any ideas?

So your saying the SES light comes on when you go up a hill and you clear it by disconnecting the battery? Scan the car for the fault codes, they will be stored in Memory even if the light isn't on. this will pinpoint your problem. A local auto parts store will scan them for free. Post the 4 digit code back here and we'll get you some more info.
