I had a similar problem, it turned out to be the coil. It would hesitate and miss like crazy until it warmed up a bit. The coil pack had numerous small cracks on it causing moisture to get in.

Sometimes they're hard to see. Check the underside for cracks when you take it out. I had a few that were impossible to see until I removed it.

no cracks on the coil pack but the plug wires did have some frozen moisture on the ends (prolly from undersprays at the car was, so i took the wires and coil pack out, checked them fro correct resistance wiped them all down and put some dielect on them and put them back, didnt have the problem yet :)
