Spark Plug Install Problem!!! I have a 02 SS with 42k, a loudmouth and a lid. Today I installed the tr 55's. I kept the factory wires. I gapped them at .055. Everything seemed fine at first. Then I notice that under a load and full throttle it misses. I get a flashing SES light.
The wires look fine. Could I have damaged them while removing them. They were difficult to get off and I had to pull on the wire instead of the boot on many of them. Has anyone heard of this problem? Any help would be appreciated.

Umm, flashing SES light is a definete sign of a miss... I have heard recently of people having problems with NGK plugs. I havent had any issues with mine.
Check all connections and verify that all the plug wires are seated all the way in the boots. I replaced my wires with aftermarket when I changed the plugs.

My money is on #8 plug. That one is a bitch to change and the easiest to crack. Pull off your plug wires and inspect the plugs. Should be easy to see if a cracked plug is your problem.

NGK are darn good plugs. But if you cracked the insulator, that would give a misfire.
Make sure all plug boots and coil ends are plugged in tightly.
Tip: when you change plugs, use some dielectric insulator compound inside the plug/coil boots (don't put on the contact surfaces). I've changed plugs at least 4 times with my MSD wires and never had a problem.
#8 plug is -easily- changed from the bottom with the front wheels on ramps.
Luck,
