adamzan Posted October 29, 2013 Share Posted October 29, 2013 That gap is slightly out of spec but it isn't causing your issue. Plug gap changes gradually. Link to comment Share on other sites More sharing options...
Precise1 Posted October 29, 2013 Share Posted October 29, 2013 Agreed with the above. I have pulled spark plugs out with .100" gap (electrode basically burned away) and the Pathfinder still run fine so I am certain that is not the issue. Also, the gap should be .032" (32 thousandths of an inch), not .32". Just clarifying... B Link to comment Share on other sites More sharing options...
LOVELADY Posted October 30, 2013 Author Share Posted October 30, 2013 I looked under my hood last night while it was dark cuz that's when I got home and and while she was running I saw the spark plug wires lighting up just the wires are they suppose to do that and if not could this be the problem Link to comment Share on other sites More sharing options...
ahardb0dy Posted October 30, 2013 Share Posted October 30, 2013 Yes, if the plug wires are bad they can be arching against metal and the engine will lose power , this is what I said previously happened to me in my sentra, time for new wires, when you change them I would pick up a small tube if dielectric grease, squirt some into the end that goes over the plug, it will make them easier to get off Next time .

ahardb0dy Posted October 30, 2013 Share Posted October 30, 2013 No they shouldn't do that Link to comment Share on other sites More sharing options...
adamzan Posted October 30, 2013 Share Posted October 30, 2013 Time for new plug wires! Or if they are new make sure they are on properly. Link to comment Share on other sites More sharing options...
LOVELADY Posted October 31, 2013 Author Share Posted October 31, 2013 I changed my spark plug wires today and these are still flashing like the old ones and it don't run any better Link to comment Share on other sites More sharing options...
Slartibartfast Posted October 31, 2013 Share Posted October 31, 2013 Where's the flashing coming from? The connections, or the wires themselves? Link to comment Share on other sites More sharing options...
LOVELADY Posted October 31, 2013 Author Share Posted October 31, 2013 on one of them the spark plug and wire touch but the other flashes are on the wire it self Link to comment Share on other sites More sharing options...
Nissanland Posted October 31, 2013 Share Posted October 31, 2013 What's the brand? Where did you get them? Are they the best, highest resistance wire's available? Might need to get a refund and get from a different supplier..they shouldn't glow/spark off the wire and with the boot covering plugs you shouldn't be able to see the spark there either..

LOVELADY Posted October 31, 2013 Author Share Posted October 31, 2013 I bought them from O'Reillys auto parts and they where the only brand in stock Link to comment Share on other sites More sharing options...
ahardb0dy Posted October 31, 2013 Share Posted October 31, 2013 Anyway you could take a video and post it ? Do you hear a clicking or snapping noise when you see the flashing ? Link to comment Share on other sites More sharing options...
adamzan Posted October 31, 2013 Share Posted October 31, 2013 Make sure they are on all the way and if they are take them back. Probably a defective set. Link to comment Share on other sites More sharing options...
Nefarious Posted October 31, 2013 Share Posted October 31, 2013 Take the wires back and order a set of ngk wires. Ngk wires are the only thing comparable to oem. Glowing wires are not good. I ordered my ngk wires online for around 65$ if I remember correctly. I would also finish your tune up. Clean the maf, change fuel filter to a 199X 300zx fuel filter(3 years is old for a fuel filter), regap your spark plugs to .34-.36, hold your air filter to the sky, if u can't see a lot of light through it, then replace it. You should also check your grounds. You can physically check them to see if they are broken but best thing to do is use a multimeter and do resistance tests from various metal points on your truck. Missing/weak grounds will cause all sorts of issues and is basically free to fix. If you find more than 1 ohm between any two metal points, you have grounding issues. You want no resistance in the ground circuit of your truck and its surprising how many times this is the problem on older vehicles. Also check your vacuum lines. There are only a few on the drivers side of the engine bay. Link to comment Share on other sites More sharing options...
ahardb0dy Posted October 31, 2013 Share Posted October 31, 2013 What's up with using a 300zx filter ? Link to comment Share on other sites More sharing options...
LOVELADY Posted October 31, 2013 Author Share Posted October 31, 2013 this is second pair of brand new wires I bought and still lighting up Link to comment Share on other sites More sharing options...
adamzan Posted October 31, 2013 Share Posted October 31, 2013 Is your distributor cap in good shape? Has it ever been replaced? They are pretty cheap a long with the rotor, something like 20 bucks for the set. Link to comment Share on other sites More sharing options...
LOVELADY Posted November 1, 2013 Author Share Posted November 1, 2013 no I have never replace my distributor cap. Link to comment Share on other sites More sharing options...
Nefarious Posted November 1, 2013 Share Posted November 1, 2013 (edited) .034-.036 is not a large gap. my 240sx requires .040-.042 gap. i run .036 on my vg as I found it runs better there and has slightly better fuel mileage. a z32 fuel filter is the same price as any other one and it has a massively increased flow path and better filtration. I use z32 fuel filters for all of my vehicles. they last a lot longer and will allow for more fuel flow when later power upgrades take place Edited November 1, 2013 by Nefarious Link to comment Share on other sites More sharing options...
ahardb0dy Posted November 2, 2013 Share Posted November 2, 2013 Precise was referring to the gap that was typed incorrectly as being a large gap, it was typed as 0.34 - 0.36, no the 0.034 - 0.036 Link to comment Share on other sites More sharing options...
Nefarious Posted November 2, 2013 Share Posted November 2, 2013 (edited) Oh, my bad! I didn't even notice I lost some zeros up there.10 hours of second year industrial automation technologist program and I'm pretty shot for numbers and math during the evenings of the weekdays. Lol.
