cant figure out hesitation
 

Hello i have been fighting this now for three weeks. Every time i go to the track my first run the car spits and sputters and runs about .03 slow. Then after that it runs fine the rest of the day. Just wanted to see if anyone had any ideas of what could be causing this. I dont think its loading up because my 60ft times are normal but my 60-330 interval is what is slow. Any ideas would be greatly appreciated. Thanks, Nate
