i'm confused, is the CEL light flashing, or are you trying to make it flash?
if it is flashing, don't drive it the engine is proper bolloxed,
if your referring to the Traction control and stability control and you want to make the lights flash, turn off traction control.
to be honest when pulling away, you shouldnt have any flashy lights apart from the TCS and ESP if you have to much power and your spinning the wheels.
when you stab the throttle hard, are you keeping your foot on it or is it just a jab, if the revs are dropping it might be because you've taken your foot off the pedal.
also remember the car throttle is drive by wire so no throttle cable, the car will self adjust to what it needs etc.
but admitedly what you've written makes no sense what so ever.
