the idle in my gsr has been fluctuating when i start it on cold days, it'll go up to 2k and back down to about 500k pretty rapidly; anyways now its dropping so low when i push in the clutch to put it into first at a traffic light or somthing that the car is dying out on me. Its not throwing any codes at all and theres no vacuum leaks, just wondering if anyone had a clue about what the problem could be
