Spark plug gap for 94 Nissan Altima

My wife told me her car was running bad so I pulled each spark plug wire till I found the problem. When I put the wire to ground I am getting spark, so I am pretty sure it is a bad or fouled plug. I need to know what to set the gap to when I go to install them.

JD JS45 walk behind mover. Starts, runs fine for 5 minutes, then stalls, won't restart till i pull the spark plug and cool the motor, plug down. then same thing starts, runs for 5, stalls.

Probably either a fuel or a spark problem. You need to check for the presence of a good spark immediately the engine stops - by using a spark gap, a spare spark plug or a propriety spark indicator.

If the spark is found to be absent the fault is likely the ignition module but check all connections and the stop switch operation before replacing.

If the spark is present then the fault is probably fuel-related and is the sort of thing a tiny droplet of water in the carb could cause...

Why does fuel appears on the spark plug?

No fire to that plug , could be coil wire or plug itself,,or Bad fuel injector, or computer that runs the fuel injectors,, or if is throttle body pinched wire under breather or bad control module,, and if its carbruated float stuck needs rebuilt,, check make sure your getting fire to the plug first,, pull the wire off and put a xtra plug in the wire,,, make sure its touching metal for ground, crank the car see if it sparks,,,if it does its more than likely it is somthing stated above

Hello, I got the silent shaft, timed with the cam, crank and oil pump, thank you for the help with comments. now that it is runnin, it runs rougher then before i replaced the water pump and timing belts...

The only way to tell if you have a ring or valve problem is to do the compression test as it the best place to start . Once you have eliminated the compression from the equation then you can concentrate on why the cylinder is getting more fuel than the others. I would be checking for vacuum leaks for the rough running as an incorrect fuel / air ratio will cause missing. We cannot fix everything but we endeavour to point you in the right direction so that you can fix it.

Missfire cyclinder 1

You are going to need to borrow some tools or go out and buy some to run some quick tests. If the misfire is in cylinder 1 ONLY, the easiest thing to do is to check spark, (spark plug tester).
  1. Put the spark tester into the plug wire and have someone crank it over. Make sure the plug tester is grounded to the block or some metal bracket, otherwise you could damage your coil. IF you don't have spark it could be due to a bad ignition coil. If you have spark at the wire and not the plug then you have a bad plug. IF you have spark coming from the coil wire but not the spark plug wire then you have a bad spark plug wire.
  2. If you see there is spark, the next step is to pull the plug out and test the plug itself. Plug the spark plug into the wire you just tested and pull the fuse (or relay) for the ignition or fuel pump. This will keep the car from starting, but will still allow you to see if the plug is firing.
  3. Also check the plug to see what condition it is in. Has the car been serviced recently, check all of the things that have had serviced.
  4. If you have spark the next thing is compression test. Screw in the compression tester to the spark plug hole in the head. Crank over the engine 3 times. Read the specification and look it up to see what the specification should be. Anything between 115-150 should be acceptable. IF you have any doubts test other cylinders to see what they are running.
  5. The last thing is to check for fuel, that is if you have found spark and compression. Locate the fuel injection port, on some VW models they are not used so consult a service guide if you're not sure.
