Had a whistle develop at idle so I checked the vacuum lines on the intake tube. Discovered a small crack in the resonator that sits above the coils. I decided to try a $20 4.7 Tundra/Sequoia intake tube on the Cruiser.

The Tundra/Sequoia intake had the 4 ports needed to hook up the vacuum lines.
- The PCV hose hooked up without a problem.
- The Power steering idle line hooked up with a little rerouting.
- The fuel regulator and line to Charcoal canister needed extended.
I notice a little more intake noise at 3,500 RPM.
