That being said, once the gunk starts to build up, the swirl flap is forced to work against increased resistance.\u003c\/p\u003e\n\u003cp\u003eGiven enough time, the flap will reach a point where the resistance is too much. Interestingly enough, it’s not the flap that goes first, but rather the cam lever that activates it. The lever is, you’ve guessed it, made of plastics. The result is a stuck flap and an engine that has suddenly lost its ability to fine-tune intake timing.\u003c\/p\u003e\n\u003cp\u003eThe resulting symptoms often include\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eloss of power\u003c\/strong\u003e,\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003emisfires\u003c\/strong\u003e,\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eextremely rough idle\u003c\/strong\u003e,\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eengine\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u003cb\u003ethrowing\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eP2006 codes\u003c\/strong\u003e, and a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003epersistent check engine light\u003c\/strong\u003e.\u003c\/p\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0369\/6505\/6571\/collections\/variable-intake-manifolds.jpg?v=1715080814","url":"https:\/\/www.autoignite.co.nz\/collections\/variable-intake-manifolds.oembed","provider":"Autoignite NZ","version":"1.0","type":"link"}
