misfire problems
went to drive my truck today to go get brakes for my dads truck and was letting it warm up while i cleaned the snow off of it and when i got in it to leave the check engine light was on, when i pulled the code it was a cylinder 5 misfire detected, it did this when i got the truck, but since then i have replaced the bosch platinums and now am using brand new champions, any ideas what could be causing this problem, and how to make it stop, it only seems to happen when the truck is started after being given a chance to cool down, and then wont do it again until it sits, sorry for the long post and any help would be appreciated,
almost forgot, driveability is not affected at all by this problem

RE: misfire problems
i doubt it bc i personally gapped each one of them so that i know they are the right gap, and then i switched it with the plug in cylinder 3 and have not gotten the error on a different cylinder, just on cylinder 5 im starting to think that its something with the cylinder when its starting cold, any ideas???

RE: misfire problems
i only changed the plugs as it has been below freezing here in jersey lately, most of the time single digits, putting the new plugs in took an hour to do 1 or 2 plugs at a time then run inside and warm up, i was planning on doing the wires once it warmed up a bit, and no i did not lube it at all, what do u suggest using, and where is the distributor cap so that i can check that out for connectivity as well as the plug end and any more ideas would be great thanks
