Hello. Welcome to Just Answer. Please allow me to assist you. With 174,000 miles on it, it is very likely you have some carbon buildup is various places in the engine. Fuel injector cleaner would be a very good idea, but, you need a cleaned to remove carbon in addition to cleaning the injectors. The absolute BEST product that we have found is a chemical manufactured by the BG company. You need to find and purchase a couple cans of this product: BG 44-K. Add one can to a full tank of gas and run the vehicle, using as much fuel as you can mileage wise (the product loses strength if it sits). The fill the tank and add the other can. There is a link to find the nearest BG retailer closest to you; just follow the onscreen instructions: https://www.bgprod.com/find-a-shop/
