Does anyone have a stuttering 5th gen SHO? I was driving for maybe 10 min and stopped at a red light. I gradually take off from the light and cruise with traffic for a while. When i try to mash on the gas, the car hesitates and it feels like the transmission isn't engaging. It speeds up really slow like a creep. When i hit it for the second time, it takes off like normal. It has only happened twice. I purchased the car with 38k miles. It now has 42k miles. I don't know if the spark plugs have been changed with the previous owner. I have an Unleashed tune with methanol. I did not have the methanol installed when it happened.
