Default Spark plugs are glowing at night!

I have E3 spark plugs and tonight I noticed that they glow whenever it's time for that plug to fire. I also have a slight misfire when under part throttle. Is this normal for a spark plug to glow WTF???

Throw those junk *** E3's in the garbage where they belong. And how do you know they glow when it's time for them to fire since they do it tens of times a second? Or do you mean they are sparking outside the porcelain?

If the metal part of the plug is glowing, you may be running lean, do you have a CEL on?

Your first issue is the fact you used E3 plugs to begin with. As stated above junk those POS's and get some NGK's or Autolites. E3 quality if for **** and I helped a buddy put some in his F150 last year. 2 were cracked out of the box and 2 more quit in the motor after 20 miles - zero signs of defect just stopped firing.

Glowing is not a normal function of a spark plug, lol. As said earlier, take the E3s out, throw in a new set of NGK TR55s, gapped at about .48-.50, and see how she runs.

I don't know about gapping them at that my motor missfired really bad with the plugs gapped there! I would stay between .35 and .40. I like the NGK's personally.

Due to my po never doing any maintaince on my car, and my lack of knowlege to this fact, my car had about 105k on the stockers and they were all about .75 thousandths. I put the platinum version of the tr55 gaped about .55 iirc, and ran like a raped ape afterwords. The problem I have with the e3 plug "voodoo" is how did they change the laws of electricty? Electricity goes to the shortest path and least resestance, so having mutiple grounds won't have the effect that they show in their animations on their commericials

They did just fine in my car at .48 before I put the spray to it. I run a .35 TR6 now.

The porcelain is glowing. And the glow fuclutuates when it receives a spark. I don't have an MSD box just the coil, so it only receives one spark per stroke... I guess the plugs are bad... lol the check engine light was removed when I bought the car...

A soft blue glow is normal. As long as it's not completely jumping and leaking it's okay. Regardless I would change those shitty-*** plugs ASAP.

Also check for corona staining (brown ring around the base of the insulator).
