Engine Performance problem
2008 Chevy Epica 6 cyl Front Wheel Drive Automatic 6000 miles

the engine starts normally when cold. Shortly after begins coughing and stalling. Dies on accelerating. The behaviour gets worse with lowering ambient temperature. When the engine temperature reaches about 40 deg continues running normally. Checked engine compression, fuel pressure, fuel quality-OK. Replaced airflow meter(MAF), spark plugs and coils, EGR, fuel injectors, engine ECU, throttle cleaned. No air intake leak through intake manifolds. Exhaust not blocked. No trouble codes.
Thanks in advance.
