After installing my JG 1001 cam, the car will die when I start it up while it's warm...unless i press the gas down and keep the revs up for a min or two. But the weird thing is, when it's all warmed up and i've been driving, it'll idle fine. Also sometimes when i start her up cold, let her warm up for a few mins, blip the gas to drop the revs, it'll die. what gives? but then if i drive it for a couple mins after that, it'll idle fine.
