    EFI Fuel Injectors

    Well, I replaced the alternator, and now back to my real problem. I have a miss. And i don't think it's timing. It's at idle and a certain rpm. he car shakes. A if no fuel. So what I am wondering is, how do I check a fuel injector to see if it's receiving voltage? And Can i just use that marvel mystery oil in the tank and it'll clean it out? How long will it take to see results? And is it okay to use used fuel injectors? Also, if I have to replace one/all of them, where's the best place, with a good price to get them at? Please give me suggestions. I am in need of help.

    to test an injector unplug it and see if the RPMs drop at all.

    I'd just run some decent injector cleaner through it for a few tanks. Many of us has stock injectors in fine condition if you need any.

      Could it be timing?

        Not used ones? Well it doesn't matter, how much if I were to get them from one of you guys/girls?

          Dunno, I threw all of mine out....

          I doubt it'd be timing. Could be plugs and wires...

            Shakes like its running out of gas. but it's not, the gauge works and I just put gas into it. So I assumed the fuel injector.

                if you absolutely need new injectors...

                that's where I got mine. Seems they've gone up in price since then, but they work great. Half the price of regular parts houses.
                But like lincolnmania says, make sure all those ignition parts are good before starting anywhere else. I'd even add a new distributor and TFI module, but that's just me, because I replaced those on both my wagon and truck, and they made a world of difference like you would not believe. Took my 6 cyl F-250 from a dieseling, backfiring, no power dog to a get up and go screaming banshee that surprised the living crap outta me.

                  Okay. I'll give it a tune up, but if it's not that, and it is a dirty injector, can I still run that injector cleaner through the system with the new fuel filter. I mean won't the gunk in the gas tank mess it up?

                    injector cleaner won't hurt the filter. If there was any junk in the tank already, it would be picked up whether or not you put injector cleaner in.

                      oh okay. But should I run it through before or after I get a new filter?

                          okay. Thanks. I'll some and run it through and see what happens, then I'll tune it up.
