the car is a DD and runs great. it only dies after i race. i can floor it in 2nd hit 3rd and let off...the car is fine. but if i start from a dig shifting at 5800 rpms, it will run beautifly through all the gears until i let out of it at the top of 4th gear around 6000 rpms. then the car dies. i have no clue what is causing this please help. it sucks having to start the car slowing down from 120 at the end of the track or on the highway. :shrug:
