Which vacc. line and what size engine? Vacc lines are usually plugged into a connection on the intake manifold.
On a 1994 Chevy Pickup 1500, the manifold absolute pressure (MAP) sensor is typically located on the intake manifold, near the throttle body. The vacuum line from the MAP sensor connects to a vacuum port on the intake manifold, which allows it to measure the manifold pressure accurately. Ensure the vacuum line is free of cracks or leaks for proper sensor functionality.
