2011 Aveo idle problem only cold
 

Hi all,

I bought a 2011 AVEO 1.4 LT (F14D4 / T255 Hatchback) but I found the little(?) problem.

if I starting in cold, idling fluctutating but after 2-5 seconds the problem dissapears:
Sometimes stronger sometimes weaker error occurs.

i tried cleaning the throttle body and i tried relearn idle the following description: Idle Issue... but when i start engine first, the problem are stronger for 30-40 seconds but after 30-40 seconds the problem dissapears. After i restart engine in cold, the problem are same. SCAN 100 diagnostic showed no problem. Along the way there is no problem.

Throttle body cleaned
Air filter changed
Fuel filter changed
Spark plugs changed

Pls help me, i'm clueless.

Sorry my english!

Thanks,
Szabolcs
