I don't know what is wrong with your Nissan but I
do know a trick to bring back a going dead or a
dead cylinder. You take the spark plug out of the
cylinder that has the problem and you put that red
Marvel Mystery oil in the cylinder that's dead or
going dead and let it sit overnight and then put your
spark plug back in after that and it sometimes
revives a dead cylinder or fixes a cylinder with low
compression. I don't know why or how, but it does.
I've used seafoam to clean the engine out on cars
before too and that sometimes fixes odd problems.
U have to be really careful when u do that though
because you have to find the Intake line on the
engine that will feed all the cylinders. If you get the
wrong line , you can destroy your engine. However,
if you find the correct Intake line and put a hose
from the seafoam to the intake line and let it suck
the seafoam in until it starts to choke itself out and
then pull it out of the seafoam and keep doing this
repeatidly .... Your car will start to smoke because it
is cleaning all the built up carbon and crap in.your
engine, out. It smokes horribly bad though so be
prepared. When it ceases to smoke, your engine is
clean of all the crap that builds up inside over time.
That sometimes fixes a lot of odditties to do with
engine performance and it sometimes fixes the little
'glitches" that you don't have explanations for. I
don't know if this will help you, but I've used both
tricks and they worked for me to solve some of the
problems Ive had with my vehicles in the past.
