what are your O2 readings at idle sounds like your running maybe a little rich to me
the trucks tend to be running rich outta the factory

NO the EGR is totally unplugged, however, it is trimmed. Plus I am throwing a misfire code so that is not the EGR. I am still concerned that that one plug is not burnt at all.... I am curious how you can tell which cylinders are misfiring?

Did you try putting your old plugs back in to make sure it's definitely the plugs? That would eliminate the EGR as a possibility, and would coincide with Maxmumboom and John's thinking...

In autotap, look for current misfires Cyl #1, #2, etc... log all 8 cyl.

check your plug wires

will did the egr mod and the plugs at the same time so it could very well be something to do with the egr mod.
since he unpluged the egr could it have been in an open position and now allows exhaust into the intake at idle? i don't see this as very likely but who knows, i could see a vacume leak prety easily though, the way that egr hose conects to the intake is super cheezy.

egr mod = pain in the ***

you have to PUUUSSHHH that tube back in there, cant do a half *** job on that one. i ran mine at .35 for a while and idle was no problem at all. just be sure the tube is pushed on there though.

as far as the other part about letting air in at idle, not sure on that one

You might want to check your plug wires. Its possible that one was damaged when you pulled them off to change the plugs. Its pretty easy to pull them apart at the spark plug fitting where the wire crimps. Past experiance makes me mention it <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

Did you try your old plugs? try those Denso Iridiums, there nice. I agree that you could have f-ed up the plug wire, it now seems mor evident that it may not be the plugs, and some thing else. maybe the coil?

HEY GUYS FIXED IT!!!!! <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" /> <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

It was a vacuum leak at the damn EGR hole. So I took the egr tube out of the intake and plugged it up with a custom plug hahahahah. Custom plug consists of a bathtub stopper held in place by a metal plate!!! WORKS GREAT!!!! HAHAHAHAH <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
