Thanks.
From what I gather so far it's a step further than the injector replacement I just did, so should be fine.

Is that a folded gasket? This appears to be a failure on a repair done? This did not come from the factory this way right?

Glad you finally found the vacuum leak. Those fuel trim percentages don't lie.
