Re-seat them again and make sure the O-rings are new replacements for a proper seal
Agree: I had two go bad in my '96. Replaced them both and used new O rings. It solved the problem. My mechanic used some Vasaline type stuff to lube the O rings when she installed them. I don't know if this is absolutely necessary or not, but they
never leaked after we twisted on the injectors a little bit to get the O rings really seated. If the injector still leaks, I'd replace it. It's a $75 part, but worth the piece of mind and the improved gas mileage. Use a new O ring if you do replace the injector.

1997 Pontiac sunfire injector number one leaks after seals replaced?
I had two leaky injectors in my '96. I tried replacing the O rings and it helped, but didn't solve the problem. I ended up replacing the injectors. That was about a year ago and the injectors were about $75 each at Auto Zone. For what it's worth, my mechanic helped me do this job. When she put the new injectors into the seats, she first coated them with some Vasaline lookin' stuff. I'm guessing that the lube helped to get the injectors in smoothly and maybe sealed the injector to seat surface. FriPilot
How do you change injectors in 2005 dodge cummins?
My best advice, born from owning quite a few Cummins' powered vehicles, is to take it to a Cummins mechanic. If the pressures through the fuel system gets out of sync you can burn up the injector pump and then not only are you replacing the injectors, the pump and the lift pump. Mucho donero...

I've changed injectors on my '96, with help from my mechanic. I would assume that the procedure is similar for your car. It's a pretty direct job, but my best suggestion is to pick up a Haynes or Chilton manual. They are very good at showing and telling about injectors.
How do you check fuel injectors on 1994 ford escort?
With the engine running place a mechanic's stethoscope or screwdriver against each injector one at a time and listen for a clicking sound indicating it is working. IF an injector isn't operating or sounds different from the other 3 turn off the engine and take the electrical connection to the injector. Check the resistance with a DVOM across the terminals of the injector. It should be between 11 to 18 ohms. If it's not within this range replace the injector.

Do fuel injectors involve misfire?
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
What could mean check injection?
The injectors could be clogged, the wiring harness on one (or more) of your injectors is loose. Take it to a mechanic to be sure.

It could be a vacuum lock. This is the easiest to diagnose. Try replacing your gas cap and see if that helps. If not, it may be a clogged fuel line or fuel injector line or nozzle. You'll have to take it to a mechanic to have this checked out.
