my car is feelin a bit sluggish now and im not really sure whats going on.when im on a roll at around 30 mph and i floor it,i cant even feel an immediate response anymore.the last oil change was 2500 miles ago and im not sure if the dealership did a tune up before they handed it to me.i got it with 88500 miles and now it has 94500 (6000 miles within 4mos!!)would cleaning the TB make a big difference.and also,im gonna check on the spark plugs and see if theyre filled with carbon,as soon as i can.what services are necessary at 90k for a 96 maxima?one more thing,when am i supposed to change the knock sensors and O2 sensors?do i have to wait for my CEL to light up?

My suggestion would be to start with the cheapest route(s) first. Cleaning the throttle body is easy to do and does make a difference. Also if you haven't changed your spark plugs I would say after 94000 miles they need to be changed. And while you are at it change the fuel filter.

All of these things are easy to do, and they don't cost a lot of money. I did them all in one weekend and noticed a BIG difference in the way my Maxima ran.

Here's a website that helped me out alot in what to do at 60000 miles. If you haven't done any of these maintenance services, it is probably a good place to start. Good luck.
