My JK with 145K miles ran rough for about ten seconds upon start up yesterday but then ran smoothly. Threw DC P0205 "Fuel Injector 5 circuit". Dealer found pressure too high in that injector. I had spark plugs and ignition wires replaced and fuel injectors cleaned in 2019 at 126K. Dealer is suggesting replacing all injectors but we are in Montana until September 18 and then head back home to Arizona where I have a great local repair shop. Question is do I have the dealer replace just the one fuel injector now? He said the others may last another 10K although I just read online that fuel injectors usually have to be replaced at 50K-100K miles. If I have just that fifth injector replaced now should I have them clean the fuel injectors and do a tune up? Oh, one other minor detail. We are thinking about selling it and ordering a 2023 Wrangler Unlimited but that wouldn't be until sometime next year...but I just love this one and don't really want to do that.
