Exactly the same problem with my local duties car, Chevrolet 800CC.
Same problem every morning. Even during day time, if car parked for more than 2 hours.
Same hesitation during acceleration also... Even more in the eve, when I turn on lights...
My spark plugs are fine. Tuning is done. Car only driven on Petrol.
Tapets also were adjusted few months back... Still problem persists...
I now have serious suspicion about the status of the injectors....
