[QUOTE="jps043, post: 15666774, member: 143561"] I am going to do my best to explain the "issue" I am encountering so please bear with me. For the past few months, I have noticed that when attempting to hold a consistent RPM while driving, it sounds like and feels like the vehicle is sputtering. In other words, it almost seems like the throttle body is constantly opening and closing because I can feel and hear the power coming and going. The ebb and flow is very minuscule, but still certainly noticeable. I have not received any CEL's and the car is certainly still drive-able but this "issue" has me concerned. Does anyone have any thoughts on what this could be? I appreciate any thoughts you all can provide.
