1995 Oldsmobile 88 Royale 3.8L Poor Idle Quality
Posted to GM Driveability on 5/18/2006 13 Replies

Hi again guys. We have here a 95 Olds 88 that came in for a 3.8L engine swap. After installing a 3.8L from a 98 monte carlo, the engine now has an annoying vibration. The supplier swears the engine ran perfect with no hint of a vibration.
