Ok here is my prob. Whenever I turn on the car weather its been warmed up or it is cold. The car is constantly jumping, the idle is jumping up and down and so is the car. It is like it is chocking and it cant breath. I dont know what the prob can be. The funny thing is that some times it does it before the car has time to warm up and then it goes away. Then it could do it the other way sometimes to. It will do it after the car has already warmed up. Can anyone analize this problem cause it is now becoming a problem for me and frankly anoying, I dont know if this is hurting my cars engine. Please help
