I think I need to change an injector, but I have no idea how to go about it, special tools, etc. The specific injector is #5. (Front drivers cylinder). Help appreciated!

Thanks,
Eric

 

There are 2 srews that hold the fuel line onto the intake manafold. Remove those 2 screws, and lift the fuel line. Unplug the injector, and pull it straight up and off.

Then reverse the procedure, Make sure all 4 of the injectors seat into the fuel rail when you push the fuel rail back onto the injectors.

A little bit od dialectric grease or silicone on the O ring will help it seat in and seal up.

 

There are two 8mm bolts which holt the rails to the intake manifold. Remove them and lift up on the fuel rail. Lift the injector out of the hole.

 

I have a misfire/stumble.

Previous plug had crust on it a bit. When I pulled new plug, it was wet.

I changed coil pack, same problem. That's why I suspect injector. IS there a way for me to verify and say 'yep, it's the injector' before i spend the $100+ to replace it?

 

Is it gas or antifreeze?

 

That I don't know, I wasn't smart enough to actually determine what the substance was. I don't see how it could be coolant, as if it were coolant, wouldn't the rest of the plugs be wet?

 

No, you could have blown a head gasket or something.

 

Swap injectors with an adjacent cylinder..

If the problem moves to the other cylinder, you've found the problem.. If the same plug is still wet, you have a different problem..

Also, make sure the O-Rings come out with the injectors... Sometimes they stick in the rails.

Ugh... I hope it's not oil or antifreeze. Good idea on the swap... 'DUH!' Thanks, I'll try this tonight.

 

Be sure the fuel pressure is bleed off....
