Hi:

I have a Maxima GXE, 96, 86k miles. When it was 56k (30k ago) I did a 60k maintanence (plugs, fluids, filters and engine tune-up). Do I need an engine tune-up now as 30k passed? Well, I do not see something bad's happening, the car runs good, may be a little bit more slower at start when accelerating than 30k ago and may be an MPG decreased a little bit since that (from 23-25 to 20-23). I am just wondering is tune-up a recommended procedure after 30k (good to do) or you better don't tuch it until something wrong happens? Is tune-up
a procedure that you need to do only at Nissan dealership or it is common?

The dealer also provides "fuel injection service" for $98 and "throttle body service" for $85. How to tell if I need this and how big may be improvement after that?

I am not a pro in cars at all, I just push pedals:-)

Thank you!

Best regards,
Maxtmp.

 

read the Maintenance thread up top. that should provide some pointers. Also, get a Haynes manual...it will provide all the necessary info you need to maintain your vehicle...

 

At 86K it might not be a bad idea to go for the fuel system and throttle body service. I had this done on my old Honda, made a huge difference in power and smoothness of the engine.

As far as a tune-up goes, just change your air filter right now.

 

When you said filters, did you mean the oil and air?? If so, also do your fuel filter.

What do they do for the fuel injection service?
