Review on High Performance Yellow Fuel Injector Kit 0280155700 for 4.0L Jeep Cherokee, Comanche, Grand Cherokee, Wrangler 1987-1998 - Pack of 6 by Kevin Griffin

Still trouble code for #1 (P301)? - definitely forgot. many other components replaced. (like CPS, TPS, F/R O2 Sensor/Fuel Pump/?), eventually replaced the original injectors with them. The originals are made of metal and are significantly heavier. They are plastic / (metal, where it matters - e.g. nozzle holes) - immediately the error disappears, the engine no longer stops. so far 7 months going strong. I don't know fuel consumption. my XJ consumes a lot of fuel, but was always well tuned, only squirts when the injector fails for a short time? throw an error. but after a while it will work fine. Overall I am happy with the performance of this item and would recommend it if you have no other options for that annoying P301 error.
