hi guys thanks for looking, ok when i just tap my gas pedal just a lil tap the rmp goes up to 2 sits there for about 4 seconds then idles back down to 1, and when your driving and coming to a stop the car doesnt idle down to 1 until after it sits idleing high at 1 1/2 for about 4 seconds then it drops down to 1, what could be making the car take so long to idle down to normal, its almost like its sticking, the throttle returns all the way but it wants to hoover at the 1 1/2 mark befor returning to normal idle at 1, oh and when i shift gears my engine jerks real bad if i dont let the rmps drop down to 1
