OK guys, I am coming to the well of infinite wisdom for assistance! I bought a set of injectors a while back from an unnamed individual (for now). He sold them to me as 42.5 009's, flow-matched (no sheet). What I have though is 6 injectors, and through the help of some older threads, I have pretty much verified that 3 of the injectors are indeed 009's as stated. The other 3 I am not sure of. They are exact in dimension and design as the other 3, but instead of a green stripe (plastic ring) around them, they have a blue plastic stripe. All six have a "2545" stamped on the opposite side of the injector from the harness connector. The green ones also have a "621031" on the one side, which I see is a correct 009 marking. The blue ones do not have this # at all. And finally, the greens ones have the correct "D3181AA" on them, but the blues have "D3181BA" in the same location. So short story long , can anyone help ID whether or not these are the same type of injector? I know you can't help me verify the flow sheet, but I just want to know if these are compatible before I plug them in and pull the pin on a potential hand grenade? Thanks to all, T/B.com is the best site going IMHO. And what is up with that Mease guy any-hoo???
