What happens here

With the engine prepared and the vehicle secured to the Dynojet dynamometer, the first dyno pull on E85 is initiated. During the pull, the engine experiences a misfire or "breaks up" as noted by the host. Visually, smoke can be seen emanating from the engine bay, attributed to the previously spilled oil burning off the hot exhaust manifold. The initial power reading from this pull is 440 horsepower, which is lower than expected.

Goal: Perform an initial dyno run on E85 and identify immediate performance issues.
