One other thing when I pulled the old plugs out they were gapped to .065 not .055 and were crap could the change in gap do this? The CEL came on instantly after I upglugged a coil so why wouldn't it come on now.

The engine PCM can tell when a coil is unplugged, which gets you an instant CEL.

ok well I tried to hook up a code reader but it wouldn't connect to the ECU I was able to check for codes and it came up empty. This just boggles my mind considering how much electronics are in car's and it doesn't even know it's misfiring.

X2!
OP, it sounds to me like you are just not getting a good connection somewhere. Check to make sure that the coils are correctly placed on the plugs and that the boots are not damaged. Did you use dielectric grease on the harness end and the boot too?
As for checking to see if the injectors are connected and firing, that is easily diagnosed with a long screwdriver. Place the business end against the injector (flathead works best) and the handle you stick your ear against. May look stupid, but this will allow you to hear nothing (which means that the injector is not working) or a rythmic clicking to the tune of about three or four clicks per second at idle, which means that the injectors are firing and thus connected properly. Just FYI, but you did connect the coil packs to the correct plugs? With a wire system cross wiring is easy but with COPS it is a lot more difficult to mess up.

I only did one plug at a time so I didn't mess the wiring up and the coil plugs can't reach any other coil besides there own. No I didn't use any grease there was still some on there the #4 boot on the pass side is torn but is still firing.

If the boots are torn change them they will screw up the coil packs I just did my plugs and changed all 8 boots for $32. It's worth changing now then blowing a coil pack later they will run alot more $32 each and always use new dielectric greese on the boots and anti seeze on the plug threads

Either of those. They will run you around $8 each, but can often get them cheaper if you buy all 8 at a time.

Seems possible to me... i don't like throwing parts at problems, but for $8 it is certainly worth a shot.

hey 01f250gold what kind of spark plugs did you use anyway what brand were they and were they copper, platinum, double platinum, or a ridium-enhanced plug
also is it possible you have a bad plug, how did they all look when u got them did they look and seem to be the same...i would put my money on the crack boots though and remember put the dielectric grease on the ends of all the springs in the boots
