Good Day:

I have a problem on my 2009 Aveo hatchback, It Always have a Hard Starting in the morning and if it start i really smell gasoline in the exhaust pipe and the vibration is very strong... after staring i must put him on 2000RPM for how many minutes because if i would not put him at high RPM it would die... sometimes i could expirence this even im driving specially im in the middle of the traffic it feels like the engine would like to die...

I already bring my car in Chev but they didn't solve the problem... its still under warranty, So i would like to know what would i do to solve the problem and what really exact problem do i have...I really appreciate if someone would help me in this problem...

FYI: The engine in the philippines is different from other county this is mine:
Model Aveo Hatchback 1.5 M/T
Engine 1.5-liter SOHC inline-4]

Thank you in advance..

cheers
