In the process of a 3800 Fiero engine conversion, the camshaft and crankshaft sensors are not utilized. This is a noteworthy detail as these sensors are typically integral components in most engine systems. However, in this specific conversion, they become superfluous. To address the resultant unused holes that would have otherwise accommodated these sensors, plugs are employed. These plugs serve a dual purpose. Firstly, they provide a neat and tidy appearance by filling in the vacant spaces. Secondly, they eliminate the inconvenience and potential expense of having to source or purchase sensors that would have been redundant in this context. Thus, these plugs contribute significantly to streamlining the conversion process, making it more efficient and hassle-free.
