Are you sure that the code is P0193, I think it may be the problem of Fuel temperature sender-G81 Interruption/Short to B+. Use car code reader to know more about info of car.

hey thanks for bringing me up to speed. ive been working on many other problems but with your great explanation i remember.
we need to check the compression on that cyl. and compare it to the compression on 2 other cylinders your choice.
but before you do this get a can of carb cleaner . and with the car idling spray around the intake manifold in the area of #6 cyl. what we are looking for is a small vacuum leak that would also act like this. with the engine idling and spraying around the intake the engines idle sould not change and if it does when you spray you have an intake leaking.
let me know how it turns out.
later
paul

sounds like you have a problem with the spark the coil may be on its way out or there may be oil in the spark plug holls shorting out the spark.
your best bet is to pull the leads out 1 at a time and and look down and check for oil if there is oil there get a new rocker cover gasket.
if no oil refit plug leads loosely and start the car remove one lead at a time slowly and look at the spark cumming out the end off the lead is it blue? if so it is ok if it is yellow and dull you have a coil problem. also check that the spark is only coming out the end of the lead as it may be coming out the side of the lead and shorting to earth,
you can do this by slowly moving the lead around the top of the spark plug holl and see were the spark is coming from

be carfull no to shock your self as it hearts like hell

good luck

ReNissan P0300


a misfire can be mechanical as well as electrical
code p 0300 is random/ multiple misfires detected
low fuel pressure is a probable cause from a problem fuel pressure regulator or problem EVAC system not venting properly causing a vacuum in the tank and starving the pump
erratic could be from valve problems on heating
loose valve seat insert/s, incorrect valve clearance from faulty hydraulic followers, cam shaft lobe failures are all part of the mechanical reason for random /multiple misfires

You may want to check for fuel volume and fuel quality. There may be moisture in the fuel. It would also help to know which cylinders it is misfiring on. Scan tool will show the misfire on live data.

More than likely its your sensor . We have been replacing a few of them especially after they get water in the gas. I have only replaced 1 hp pump in 4 years.
