Here’s the best and easiest way to remove these stuck injectors (without
any special tools):
You take the engine covers off, and loosen the two nuts that hold the
injector in place. So you should have like 3-4mm between one nut and that
metal plate that holds the injector. Do the same for the other nut.
Now start the engine and let it idle. While the engine is running watch the
injector and listen carefully. When you see the injector shake a bit and
also hear a tapping noise, it means that the engine popped the injector
out. You can also feel the injector jumping 3-4mm if you put your hand on
it.
You can also rev the car a bit (under 3500rpm) or take the car for a little
ride (if the injector is stubborn).
It is best that you stop the engine after the injector pops, because you
risk ruining the thread under the bolts. Although you risk ruining the
thread, it never happened to me and I have removed many injectors using
this procedure.
So as the engine warms up and the metal expands, it loosens the grip on the
injector, and the engine’s compression pops the injector out.
Don’t forget to grease the injector with graphite grease (which withstands
high temperature, white color) when you put it back.
Best of luck!
