Answer

A) faulty injector on a multiport engine. Explanation 1. Identify the paper test function The paper test is used to detect exhaust leaks by observing how a piece of paper reacts near the exhaust system. 2. Analyze each option A) Faulty injector affects fuel delivery, not detectable with exhaust paper test. B) Burned valve can cause irregular exhaust flow, detectable with paper test. C) Cracked exhaust manifold causes exhaust leaks, detectable with paper test. D) Bad spark plug wire affects ignition, not detectable with exhaust paper test.
