You need to properly diagnose problems before replacing parts. It could be a bad coolant temperature switch telling the computer in your car that the engine is dead cold and needs more fuel. You need test procedures. Do you have a workshop manual? Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
