ok so i got a gsr a couple of days ago and i drove it from austin with no problems what so ever and just two days ago my car started to sputter. I had the same problem with an ls that i used to have and the ls would sputter when the car would heat up...ok now the gsr sputters when its cold, it starts to run like normal when it heats up so idk if its the spark wires, the spark wires were the cause with the ls but now the effects are reversed so i dont know if the gsr also needs spark wires, any ideas?

 

does it sputter at idle, thoughout the driving speed, or on acceleration. it could be any number of things but knowing when it happens you can narrow it down

 

no it idles perfect it starts sputtering when i accelerate and even more when i dog it
