Volvo 740 Idle Speed

Hi All

I need to raise my idle speed on my B230E volvo. Can you give me some
ideas of where to go poking

Many Thanks!

Assuming you have a clean airfilter, no leaking injector seals, and
fuel and ignition systems are otherwise OK, there is an idle speed
adjuster.

It may vary, depending upon the year/fuel system you have. On my '87
with K-Jet injection, there is a thumbwheel sticking out of the
throttle body, under the inlet manifold, seen here:

These injector seals, how often should they be replaced and is it a easy
job? I've had the car for 3 years and cant say ive ever touched them
and the car is a 89.

Thanks!

It's easy enough to do. Undo the single bolt that holds each injector
in place and lift the injector out. The seals are simple O-rings that
slide onto the injector body before reinserting it into the head. Old
ones will have hardened, split, or crumbled away. You can test for
their effectiveness by trickling a little water over the injectors
while the engine is running. It the seals leak, the water will be
drawn in and affect the engine speed.

If you replace them, clean out the injector hole as well as the groove
on the injector body. In my experience, replacing the seals is never
100% effective, so I apply a little silicone sealant around them as
well.
