Every now and then, i back my car out of the driveway when i just start it up in the morning. After backing out and putting it into first gear, then taking off, my car sputters like theres a lack of power. I let off the gas, then i try again and its normal. This only happens on cold starts RANDOMLY and only after going from reverse into first gear. What could be the cause of this? I have toda b's, port flow inners/itr outers, skunk2 retainers, skunk2 cam gears. I'm afraid that it might be valve float?

 

Anyone?
