ok heres where it gets strange imo. When the a/c is on you can feel the car jerking off and on ..it feels like someone is bending a fuel line to cut the fuel feed off ..then it kicks back in ,..then back off over and over..i just replace the fuel filter..kinda nasty.new plugs.cap,button,wires are good.new alternator,new battery. im lost here.and opions? :dunno: or is this normal. as im sure it didnt do this when it was a new car.
