2.9 misfires while alternator is working.

No have replaced TFI twice along with distributor and the TFI pigtail. Still same exact running problem as described on this post.

You may get a better response if you start your own thread and detail how the problem started, and work done either before or after.
New parts don’t mean good parts any more so testing components is often necessary.

I have some problem? Did you ever figure out what was causing it to miss fire. I'm pulling my hair out on this.

I would try to get a factory tfi from a junk yard, or a few to have on hand. I've tried 2 from autozone and both do it. Even the ones from Ford dealer are not real oem anymore.
