NOW hear is the scoop I had a chip in it . a small one (toggle type 0-80-120)for about a year or so. Lost about 3 injectors. took it in on warranty got the run around about the chip. took it because you know why my mileage and power are gone.with the chip (12.8in town 16.5 hyway) Is there any way to help this problem and get around the boys down at the daelership. thanks in advance.
