Would a leaky intake pvc hose cause pl174(lean code)?only on the pass side. Car is tuned... Changed o2 sensor and ext harness and its still coming up. Looks like the stock pvc hose and vararam hose connects.. doesnt have a very good seal. So I pit a heat shrink on it... Will that fix the problem?... Can't think of anywhere i can get a vac leak. Headers are on good and tight. And i nver messed with anything else... HELP!
