I have a 93 YJ 4.0L and was just wondering how long the injectors usually last before they need replacing. If anyone has done this....are they expensive? I can change them myself, I just want to know if the parts are expensive.[addsig]

i've never heard of a fuel injector dying. i think the main parts of the fuel delivery system that need attention are the filter and pump. is there something wrong with your jeep or are you just curious?[addsig]

injectors can get clogged...you can put the jeep on a scope and see the pulse of the injectors and pin point the one thats giveing you trouble... IF you change your fuel filter regularly and put injector cleaner ( i uese STP) when you hit the hiway your injectors will last for a long time...[addsig]
