Thank you a lot spike99
I checked the car today with a computer in non-GM service shop. The computer shows "Fuel Trim System Balance in Bank1" error. The technician cleared the error. I check the car in a trip of 70 km but the light does not appear till now. I am sure it will come again because we did not fix the problem.
The question is, is this a real problem? Why do this happen while the vehicle still new and we did not use it in a heavy way?
 
Many thanks

Sounds like some good reading at:
 
http://www.automotivehelper.com/topic413259.htm
Leaking intake gasket as one problem source caught my eye.
 
http://www.autotap.com/generic_trouble_codes.asp
Found rich & lean. NO "Fuel Trim System Balance" code.
 
http://www.caranswer.info/maintenance/Engine-light-question---Maintenance---Repa- irs-.html
 
If your vehicle's CODE reader could provide you either LEAN or RICH (instead of generic word of "improper balance"), it would help even more as well...
 
The one URL suggested its OK to drive with "solid" Engine Light. But if "blinking" Service Engine Light, something very bad is happing. Each time my vehicle's got a service engine light error, I would "baby it" to my trusted mechanic. Not too sure if I would continue to drive a vehicle with Service Engin light - unless I needed to. then again, it really is your call - under Service Engine Light condition...
 
Hope this helps as well...
