Hi. 

I have an Astra 1.4 CFI car and have fallen to the dreaded enginement
management light...it is flashing code 35, but there doesn't appear to
be any obvious deterioration in performance [never been much good
since I've had the car!] apart from a 'slight' lurching [a small
increase in revs] when the car slows.

IS there anything else that might affect this fault other than the
idle control valve?

Appreciate any input.
Cheers
Garry

An air leak on the intake manifold, or a leak on any of the components that
connect to the manifold can cause this fault code.  Common problems I have
found to cause this are faulty throttle body gaskets, faulty manifold to
head gasket and dodgy thermostatic control valves for the air intake control
flap (selects whether intake air comes from the wheelarch area or from
around the exhaust manifold).

rusty throttle cable (the nipple at the throttle body) that doesn't let the 
throttle fully close, I have only come across this once, but it is possible, 
the symptoms are  right.

Sure, thanks for these replies guys, I'll take a look at the whole
idea of an air leak. Thing is, the light doesn't come on immediately,
sometimes it might be after 4 miles, sometimes after 15, and likewise
when the engine has been shutdown for a few minutes, the light will
stay off for a while before coming on again.
