Hello, I would love to help. I have a Grand Cherokee 2000, a 4.7 petrol engine, model WJ, I have had it for over two years, the vehicle sometimes shuts off in low columns. Faults that appear in vehicle P1491, P0204, P0152, P0130, P0136. It should be noted that a computer was replaced a year and a half ago and since it was replaced I had a malfunction of oxygen sensors, it turned out my jeep only comes with two oxygen sensors, a federal standard, the phenomenon that the jeep turned off that I slow down in the middle of squares started a month ago, I fixed the electric fan sitting on The radiator bypassed with relays but still the jeep turned off, I would be happy to help, what should I do.
