I've posted about this issue numerous times, but I can't get a handle on it. Lean fuel codes and stumbling/stalling. Map, maf and intake seals changed. Fuel pressure good. I don't have a tuner. What's the likelihood of a cracked intake?

Another vote for pull it. I think used ones can be found for around 300-350. Its an easy job.
If you just want to find out if its the problem, I think you can spray carb cleaner around the intake and see if you have a spike in your RPMs. Though this may not work if there is a crack on the bottom or back.

If you’re looking to replace your intake I have an LS1 intake I can sell you for cheap. bought it used in perfect shape for my swap and never used it because I got a good deal on a LS6 intake.
PM me if you’re interested.
