Part of Lesson Plan: **Vacuum Testing / Driveability (updated) by Michael Fleming

Activity Overview / Details

When four to five students have completed the drawings / labeling, give them a vacuum gauge and pliers and assign them to a vehicle. After they follow the steps in the worksheet properly, allow them to create a misfire, create a vacuum leak, or clamp a socket into the tail pipe to create a plug exhaust situation. Extra credit can be given if they recognize differences in vacuum readings with each "bug."
