Re: fuel injectors (-10sp)

>Thanks Paul, How do you remove the fuel injector?
The CSV is usually held on with two allen bolts. The other injectors are
pushed into place and stay there because of the rubber(?) o-rings that seal
them air tight. Over time, these o-rings become rock hard and this makes it
difficult to extract the injectors. You can buy injector removal tools (a
long bent screwdriver with a split end to grip the injector), or you can
improvise. What I do is use a vice grips (mole wrench) to grip the nut that
joins the FI pipe to the injector, then using a very large screwdriver, I
lever the vice grips and out pops the injector.
Check your manual to see how many o-rings are required for each injector
(they MUST be replaced if they have gone hard, otherwise you will have
unmetered air entering the CIS system). If your injectors are mounted in
shrouds, you might consider removing and inspecting these (cut-down 13mm hex
key required I think).
