Do any of you know what these hoses are for? My motor was running fine not too long ago, but when I took it out yesterday it started to bog down really badly and hesitating. It was bucking like a horse until it basically lost most if not all power. I made it to an autoparts store and changed the spark plugs with some NGKs and also the fuel filter and airbox filter. It still had the issue it even got worse. When I popped the hood on the freeway I noticed that the smaller tube was completely unhooked. I was wondering if that might fix my issue. I suspect it's a vacuum leak or maybe a dirty MAF sensor. Basically I just want another opinion on the matter. It's a 91 hatch with the KA24DE if anyone is wondering lol. But the wires should give it away.
