2000 Ford Mustang ridiculous list

Ill give u what the junk yard will give you

Start with a basic tune up. Wires, plugs, pcv.I would take the car to a muffler shop to get the catalic converter checked possible clogged. Also egr valve. And loosen the throttle position sensor and wiggle it and tighten in other position. Has jus a little play when loosen. Also check that your rear and front shocks r good if bad it will feel funny over bumps like your on a boat.I think mufler shops cheks the catalic for free, its quik and easy should be free. Forgot to say the idle control valve can accelerate motor or under iddle to. Check all vacc hoses on throttle body for bad cracked mushy to soft, unplugged etc. Change air anf fuel filter if bad. The cover on differential means nothing if its rusty dirty or whatever its just a cover. Unless it leaks oil then u will need a new gasket but thats it, easy job. And also can have a weak fuel pump but I think its not gonna be that but maybe just maybe possible lol. Good luck

Forgot to say if you need a cover for a differential u can find one in a junk just count the bolt holes and be sure its the same. Also the throttle position sensor can be found in a junk yard from most any ford older bout 90 to present. Also the cover from older mustangs as long as its a v6. Good day
