I was wanting to know if some of your cars have a weird idel? Mine will move up and down. Not much but the needle does move. Is this normal? maybe 100 rpms then it goes back down. I was also wanting to know if fuel injectors are spose to click? I have went to a few shops around town and people say do not worry about it. They say to worry when they stop clicking? i hear it when i am neer a wall and it is amplified. It is not that loud just annoying it is kinda like a squeel then when i am ideling it is a light clicking.
