started acting up a few days ago. Got a blinking CEL going down the hwy and then no CEL at all. When you first put her under a load she is as strong as ever but after about an inch of throttle she lays flat starts missing. When checking the codes i get a P0300 multiple cylinder misfire but it will not pinpoint which cylinders are acting up. Clear the codes start it up no codes, drive down the road its doing the same thing and no CEL. Head scratching for sure. Plugs coils injectors sensors cats all less than a year old. No back firing or popping she just want take the fuel. What's new? Fuel pump, cam position sensor. Everything else is less than a year old.
