[200q20v] Fuel Injectors and Oxy Sensor

[Max Conover]

Has anyone ever replaced the fuel injectors themselves ? Even after
unbolting the fuel rail from the intake manifold and taking off the fuel
lines, the fuel injectors just do not want to come out. What gives ? Any
tricks that I should know.

Also, has anyone wired in the universal Oxygen sensor, bosch 13913, into
the the original harness. If so, what connectors are used and which goes
where.

Thanks !!!!
