Can't find misfire

[Chevyman91350]

The thing with my truck is I don't feel the misfire when I'm driving. It's mostly at an idle. But even if I rev it up to 2000 rpms and keep it there it will misfire. I've never felt it while driving. Would that possibly still Be ignition module?

I've experienced what you describe here. Kinda of like a bub bub bub a bub.

You might have air bubbles in the fuel line. A complete and thorough going over of the injectors and the FPR may make it better.

If it's not a problem when driving, it's not a problem worth loosing sleep over. Time to move on to bigger and worse things.
