Nissan Repair: nissan maxima 00 ,fuel injectors., nissan maxima, feul injectors

Question
I  have a 2000 maximaSE,for some days my car was shutting off after some seconds and I have to start so many times to start the car , then suddenly after one week my car lost the power and there was no  pick up ,I took it to mechanic and he told me you need 6 coils and MAS sensor and Idle air control senser . but when mechanic saw my spark plugs he told me  change them because they were all black and rusted , even though I changed them and install original  plugs just 2 months ago.now he is telling me you have to install 6 feul injectors because they causes all this problem .and it will happen again if I don't change them .I am confused  and if I just change 6 coils , MAS AND air idle sensor and plugs , will it fix my problem ? without changing feul injectors because each injector cost 160 . the car has a rebuilt title and it was hit from the back .

Answer
Farhan,

The coils on your car are known to go bad and that is what I would replace first.  If you do the work yourself you could save a bundle.  Coils can be purchased on-line for about $60 bucks each from courtesynissan.com or rockauto.com.  I would wait on the injectors until you change the coils.  I personally have a 2000 Maxima and it is what I did.  Now, I would go with a fuel treatment and a tank of premium to clean the injectors up after replacement of the coils.
