the number 6 cylinder is located (if you are looking at it from the front of the car) it is on the left side third cylinder back from the front. you probally have a bad injector that is just dripping fuel into that cylinder.

When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.
Ex. P0401 means there is misfire on cylinder number 1
P0400 is a random misfire detected.
If you take it to an Advance or Autozone they will usually scan if for free.
By the way, if you used cheap plugs instead of platinum plugs that could do it too.
Hope this helps.

My 99 Suburban does this when I pull a horse trailer and drive over 55MPH. It will go out when I unhook the trailer and drive it around a bit. A friend told me the same light has been on in his Chevy pickup (about the same year) more than off. He has ignored it for years and no problems. Another friend who is a mechanic, (albeit a Ford guy) says the joke around his shop is that it's really the "engine ready light"! If you've had everything checked out and all you get is the misfire reading (same as mine) then get a sticker to place over the offensive light and enjoy everything else about the great vehicle you have- that's what I do!
