So I was trying to find out whats wrong with my friends car. He does not have internet access so im posting this for his behalf. Basically the car runs fine when it is cold. However, as soon as its warmed up, the car seems to shudder and turn off. We figured out a way to somewhat keep it running if we mess with the throttle but it needs to be idling around 2000 for it to keep staying on. We never bothered to drive it like that. My friend replaced the MAF and idle control sensor. He replaced the spark plugs as well.
