Okay guys I'm having a problem keeping my intake plugged when my car is running. I have a 250 motor and as you know there's two outlets. One of them i'm running my PCV valve, and the other one is plugged but for some reason when I'm driving or accelerate
the damn plastic plug comes out and then the car starts back firing and runs like hell. What's causing the plug to come out?
Is it because the plug is plastic and not strong enough to stay in? Please help.
