maybe someone on here has had this, the car seems like it runs and idles ok, just when im driving and say im going down a hill, if i put it in neutral or just put the clutch in, it drops down to idle, and idles for about 5 secs fine, then will stall, it only seems to do it when im driving, just just sitting idleing? and ideas, its an S4 T2 with an S5 JDM motor
