One more question. In the dark if i look at my sparkplugs while the engine is running i can see them being fired, the white part lights up evertime it gets spark, is this normal? I have msd setup(box,dist.,coil) i would guess it is normal, just wondering if my plugs were bad in some way??? using autolites

This is not necessarily the answer to your question but are the wires relatively new. Usually the problem lies with cracked wires. When they are old or cracked they will shine at night and you can even see them some during the day. You shouldn't be seeing the fire. Arching....This can definitely cause mis-firing during higher rpm's. Could be wrong with your application but general it's bad wires.

They are newer msd 8.5 wires the red ones. I don't see anything through the wire just the porcelain on the plug.

Sorry Cody, misunderstood you. From reading other forums about this the response was trying a step colder plug application and to make sure the spark plug gap was set correctly. Although I haven't heard of there being a problem with the glow from the porcelain.

Have you checked the plugs carefully? Maybe they were purchased by someone, used for a while, and returned for full credit.

Cody, I have seen this happen with hairline cracks in the spark plug, which could happen when they are being installed. Are all of the plugs doing this?

Is there any problems that are coming along with this, or is it just the glow that you're wondering about? Most ceramics are semi-opaque, so I don't see why this couldn't be normal operation. My car is currently in the shop getting painted, but I'll run it in the dark when i get it back to see if mine do it too, anyone else want to try?

They all do it. Most of the time you just can't see it.
