Default Running down a miss (Update)

Below is the original thread I started but never got the chance to do any of the troubleshooting. I replaced the ICM, coil packs (Series 2), and installed new TR55 plugs gapped to .055. I still had the miss and was starting to think that either my Beldens had failed or it was a mechanical problem. Well today I finally swapped my injectors for rebuilt and flow matched ones I got from Sandrock and the car runs better than ever before. No more miss and no more bucking. I wanted to post this to inform everyone to not completely rule out the injectors even though it'* rare. Thank you to all that helped out. BC rocks
