Disconnect MAP when jacking up engine? - ZR-1 Net Registry Forums

Corvette95 · 12-06-2020

Can't find the post where I read about disconnected the MAP when jacking up the engine for motor mounts....seems it would all move with the engine? Should I disconnect the MAP mount at plenum, the Map electrical plug or what exactly....thanks.

When jacking the engine in the chassis I remove the map sensor bracket and vacuum line from plenum leaving the electrical connector plugged in.
