i've got a misfire i can't pin down

it only occurs noticeably after cold startups.
severe bucking and sputtering after acceleration

throws code: cylinder 1 misfire

once the truck warms up....everything is normal
that's why i can't narrow it down

i've changed plugs (motorcraft platinums) wires, checked gap

i swapped coil packs (switched exhaust to ignition) and still does the same thing.....both coils couldn't be shot or maybe i'm wrong

i'm open to ideas....

Believe me, I had a similar problem on cold start ups. I would get the CEL during warm up and notice as I was decelerating, I would get a slight hesitation and then the engine would start bucking and the rpm increased upon stoping and settled back down to 700. I changed everything I thought was connected to electrical and still could not figure it out. What I finally did was take the truck to a reputable mechanic (which I thought I should have done to begin with and saved myself some $$$). This is where it gets weird. He changed out my thermostat and the CEL went away and the engine started running smooth upon acceleration/deceleration. Apparently the computer was not getting the right signal that the engine was at operation temp and would overcompensate with a richer fuel mix.

Go figure/worked for me

I can see how that is... #1 is right behind the water pump, so #1 stays cooler.

I would have thought the ECT tho, when they go bad, they ECU defalts to thinking its -40* and dumps loads of fuel
