If the misfires were on 2&3 or 1&4 then the CP would be the # 1 suspect. The OP tested the CP, PR was fine, SR was a little high but he did not say if it was high on both pairs or just one pair

Coil-pak. Both cyl. 1 & 3 are bad thru the coil-pak.

That doesn't seem right considering one of the coils fires cylinders 2 and 3 while the other coil in the coil pack fires cylinder 1 and 4 so usually you'd see a misfire on the 2 and 3 cylinders or the 1 and 4 cylinders not the 1 and 3 because they are fired by separate coils.

Do a compression check on all 4 cylinders. Let us know how it turns out. I fought the same issue for a year and a half just found low compression in cylinder 2 to be the issue.

coils....coils....coils

everything you've described is pointing to the coil packs

plus i had this same issue for the longest time....had a #1 missfire i could not track down....and only at idle when it was cold at first
but gradually got worse to where it missed full time at idle on #1 and #3

finally used a customer from work as a guinea pig (he had the same issues) and he changed his coils....problem solved

so i changed mine and HURRAY!! miss=gone

Definately the ignition coil packs. also when you change plugs as a rule of thumb you also change the plug wires. If that doesn't fix it nothing will.
