Ok guys, here is the skinny, 95000 miles, no smoke, new plugs, oil, ect ect, My car just started 'gurgling' when it is at idle full throttle between 1-2500 rpm but then it kicks in ok after that! What is the deal?? I do have a walbro 255, and a super afc. Could the walbro be doning this?? Or mabey my fuel filter??? Anyone had this problem?
