Alright, this morning before I went to class, I let my car warm up to running temp. On my way to school I had to downshift a lil and step on it a bit, AS SOON AS my RPM's get to around 3200-4000 the car starts to buck and jump, slow down and get faster. What the hell is the problem??! I haven't really been beating on the 6 lately so I dunno what the heck the problem is?? Anyone know?? Or have any idea?!
