As part of my troubleshooting a ‘Check Engine’ light issue in my ’94 SL500, I replaced all the small, milky-white plastic tubing around the engine… except for one line. This vacuum line goes from an ignition module (picture #1) to somewhere under the intake manifold (picture #2).

Short of removing the intake manifold (which seems REALLY silly), how do I gain access to the end of the vacuum tubing attached to the engine? The one under the intake manifold?

Cheers,
Jeff
