Subject: Diagnosing compression test


I've been suffering from an erratic idle ever since I bought my 89 900t a year ago. A dry compression test has shown that no. 3 cylinder is reading 8 bar (versus 10.3 bar for the other cylinders). A wet test brings all four cylinders up to 14 bar. Any suggestions about what mey be the cause? A broken piston ring maybe? Sounds serious whatever. Cheers, Alan.
