Nissan Repair: 94 Nissan Pathfinder, fuel pressure regulator, nissan pathfinder


Question
A question was posed to me about my sparkplugs.  If there were either brown (normal) or black, wet (fouled).  I could only get all but 2 plugs that are stuck in there.  The plugs that I did get out were black and wet (fouled).  I only recently bought the truck.  The two plugs that are stuck have nothing to grab on off to get them out.  Any suggestions?

Answer
Lukas,

If the plugs are black and wet you have too much gas going to them.  I would check the fuel pressure to see what it is reading and verify that the fuel pressure regulator works.  On the sparkplugs, I would spray Liquid Wrench or WD40 down the hole and wait a few minutes and then get compressed air to see if you can blow the debris out.  Then, using a thinwall socket remove the plugs.  There is probably a couple of things going on and one is dirt and the other is a thick wall socket interfering with the removal of the sparkplugs.
