VIEW    REPLY TO THIS MESSAGE    PRINT   SAVE   A    A  TURBO BOGGING BLUES 700 1988 posted by  someone claiming to be D. MOFFAT on  Sun Feb 7 18:24 CST 2010 [RELATED] 1988 Volvo 760 Turbowagon with 2.3 litre engine. The engine only operates 'normally' with no boost (up to 1/16" left of center) and only boosts 'normally' at 60 to 80 km/hr (3000 to 4000 rpm) in over drive. Invoking boost at any other time will cause it to bogg and quit unless I back-off. It starts and idles flawlessly. I have replaced the catalytic convertor + oxygen sensor, both forwarding and pressurizing fuel pumps, air mass sensor (from a 1990 non turbo sedan) and gas pressure regulator. My problems started when I replaced the turbo and exhaust manifold with a second hand unit from Swedish Motors in Toronto. The waste gate is free and overboost regulator appears to move when I pressurize it. Is this a fuel/air mixture problem caused by miss-matched components?
