Leaky Injector

[89 240 SOHC]

My Number 4 injector is leaking externally I replaced it and the seals but it still leaks....should I look at replacing the fuel rail or is there something else I can try??

You may have slightly torn an o-ring when you installed the new injector. Don't worry it's common. The trick is to use a lube on the o-rings and tighten down the injectors evenly on each side.

Will a Leaking Injector cause a miss in the engine? My engine tries to die whenever I'm not accelerating....I'm baffled. All sensors are plugged in except the AIV. The AIV exhaust tube is blocked off. I have a bad exhaust leak at the downpipe to cat flange.
