Reply With QuoteYour hesitation and poor idle could be caused by the mass air flow sensor.
You'll want to replace the O2 sensor and knock sensor for the sake of
emissions, performance, and fuel economy, but they probably aren't causing
your problems, outside of possible SLIGHT hesitation from the knock sensor.

95 Maxima
My check engine light is on and i found out that it was being caused by the
O2 sensor, knock sensor and Mass air flow sensor. I haven't replaced them
yet, but i did replace the fuel filter because the car was hesistating
alot and shutting off while idling at stop signs. I've checked the air
filter and housing and it seems fine, but I'm still having the problem.
Someone please give me some suggestions for my 95 max.

Replace the knock sensor 1st. Sometimes just that will make the others
go away. If not, then replace those as well.

95 maxima
my light is on indicating I replace the rear o2 sensor (downstream) and the
knock sensor. if I want to do it myself, what recommendations does anyone
have? can a amateur do it? or should I go ahead and spend the $650 they
are quoting me? are autozone parts sufficient enough or what? is the
bosch oem o2 sensors on their website the ones I am after? if so, I just
need one right, since its the rear sensor thats bad,(they say "2
required")? and the knock sensor is out? any suggestions?

Re: 95 maxima
Yes, you can do it yourself and Autozone is fine. On the oxygen sensor
it has to be the same length as the original as the oxygen sensor is a
self generating sensor. So, if you get the one that does not have a
plug on it you will have to cut the old connector off the old sensor
line and solder it onto the new oxygen sensor. Be sure to measure the
length of the old one before you cut the end off and make sure you leave
a few inches to make the solder joint. You do not want to have the wire
too close to the connector. Also, go to Radio Shack and get some shrink
tubing to make a water tight seal. If the oxygen sensor has an end on
it you will only have to plug it in.
