I have a 2001 3.8l and its running rough. I recently put in a CAI but its way to cold out to run it, so i replaced it with the stock one. All the time when i ran the CAI my stang was jumpy. It would jump in increments and would shift high. I cant figure out whats wrong. It also boggs out when stepped on, and my whole car shakes. Could this be water in my gas lines? or maybe a cylinder not firing? I just need some advice from an expert. Thanks Any Help would be greatly appreciated!!!!
