So, I have the same problem as some of you on here. Two of my injectors are not firing. I just did a full tune-up, so it's not the plugs/wires/cap/rotor. Unfortunately I don't have money for new injectors, but I do have a used JY intake manifold with a full set of injectors in the fuel rail. My question is how do I test the injectors? Can they be tested on the car while it is not running or in the JY fuel rail without being connected to anything? By running an Ohm test do you mean using an electric tester and touching one node to each prong in the connector?

I'm thinking of just swapping over the entire fuel rail with injectors from the JY intake to my car but I'm not sure if they are in better or worse shape than the (working)ones I have in there. Plus, not having yet taken off the connectors on my Max I wonder if the red top square injectors on the JY intake are compatible with my harness.

Also, does using only OEM O-rings really make such a difference? Does everyone have bad experience with parts-store O-rings?

Any advice would be appreciated. Thanks.
