Cuts off

[Saltydog13]

Replaced valve cover and gasket and now engine cuts off when slowing down and when sitting at idle. I figure I have an issue with the gasket (had to replace due to old one damaged and leaking oil) when I installed; maybe need to tighten valve cover bolts more. Anything else I need to check?

Sounds like you may have loosened or broke a vacuum hose. They get pretty brittle on the old CJs. There's nothing that the gasket can do to make the engine stall.

Being a CJ fan and having mine apart many times. It is very possible that you have a couple of vacuum lines crossed.

The only hoses I removed/disconnected are the ones with the blue tape on them. I have hooked all back up as they were so I am at a loss.
