The 93-97 Altima has a classic flaw. The distributor and cam position
sensor are 1 unit. The flaw is that the CPS, being driven by the exhaust
cam, is indirectly connected to it. In between this connection is a seal
that prevents oil from seeping into the CPS/distributor part of the
unit. Once it starts leaking, un-relaible ignition results. Solution:
replace the entire distributor-cap-rotor-base module of the distrinbutor.

Check your distributor and see if there is any oil or oily feel to it.
You could get things working temporarily by wiping away any oil if you
need to get somewhere as a temporary fix.

I am trying to diagnose a problem with a 96 altima with a dual overhead cam
engine.
the car ran fine till it was parked for 9 months.
now that is being put back in use.
when cold, it starts, idles, and drives perfect.
once it warms up, it will sputter at idle, and eventually die, and will not
restart till cold again.
I did a fuel pump test, and the pump pressure is fine, so it is getting gas.
I have not done a spark test yet, but plan to, even though I know it is now
a no spark problem.
my question is, has anyone run into this problem before?? I don't know much
about foreign cars, but believe it is either a bad coil, or a bad ignition
module.
