Cold Air Intake left open?
So, I went for an oil change and they said I needed a new air filter soon in my 10' Jeep Compass. Thought I'd save $15 and do it myself. I forgot, and changed it about 4 months later... problem was the box was open, and the filter in there was not sitting properly. Recently my car has been shaking in idol, has "hick-ups" when accelerating, and has stalled on me once. Do I need to clean the manifold, add injector cleaner, or could this be another issue all together?
