Re: No power - 940 S Auto
I would hazard a guess that your 940S has the 2 Litre engine (B200). This is
normally fairly sluggish as it has to haul a rather heavy car around and is
not really man enough for the job. It sounds as if the inlet tract could do
with a thorough clean-up including the Idle Air Control Valve. The Positive
Crankcase ventilation system could also do with a refurbish. If you do not
have a turbo on your engine there is a filter included in the Flame Trap of
this system. This will need replacing as will the smaller of the two hoses
from it's top to the manifold, the nipple it attaches to will also need to
be scrupulously cleaned to ensure that there is no blockage occurring.
The sluggish when cold may well be due to a thermostat having failed open
and/or a non-functioning cold start injector.
Is your car a saloon or an estate? If it is a saloon it is from 1992, 1993
or 1994. If it is an estate it could be from 1995.
Why don't you ask on the technical forum 900 series section of the Volvo
Owners Club website for technical help. We have a lot of knowledge available
to help Volvo owners in trouble.
