80 Row vacuum and idle issues

[meichten]

Following up from my previous cold start thread

Found and re epoxied leak in airbox around pop off valve, looks like it was leaking at some point and silicon was used in addition to the original epoxy. That ultimately failed.


This allowed the car to start and then had very little power and rough idle.
Then replaced the mcu to airbox gasket, whistle stopped after that.
Also replaced o-rings for cold start injector.


After replacing the above items the car was drivable, however idle was off.

May have one more leak.

Anyone have luck fixing minor leaks on airbox or is total replacement the only route?

For now dropped it of at the local p shop to fine tune idle as I don't have co2 sensor equipment.
