      lol.... yes Id say you might need new ones. Especially if your fuel system may have been neglected at some time.

      To change them, you have to reomove the CFI unit and take it apart. The injectors are sandwiched inside the halves. Might as well but on a new fuel regulator too, and clean the screen thats under it.
      There are O-rings and crap, and I havent dont this (and run it) but it couldnt bee too hard. just dont mess up the orings...
      yes our injectors are electronic. and expensive.

              You can try this for cleaning on the cheap:

              No gurarantees but it wont cost you much. Also, you can get new O rings at the parts store. They're on the top of the injector. Use a bit of lube to install them, penetrating lube or even vaseline works.

                Except you can't get o-rings for CFI cars. You can get 'em for EFI cars all day long, but not for CFI. Trust me, I've tried several different parts stores and the Ford dealership.

                I ended up buying generic, non-fuel type o-rings and so far they've worked fine. *shrug*

                  they're different than the O rings for the EFI cars? Hm, my injectors use what looks to be a standard boring roundy round O ring. Are the CFI injectors a different size or something?

                    Yeah, the EFI o-rings are big fat things compared to the CFI o-rings. The ones for CFI injectors are probably only 1/32" thick, whereas the EFI o-rings are more like 3/32". Those figures are just my recollections, so they could be significantly off, but one thing I do know for sure is that they're not anywhere near the same.

                        Just bring the original o-rings with you so you have something to compare with, and dig thru the parts store's o-ring stock until you find the right size. The one problem is that they aren't designed for use with fuel, so it's possible they could dissolve after awhile--you'll want to keep an eye on them. I haven't had a problem, but the car hasn't had more than probably 1000 miles on it (if that) since I replaced those o-rings.

( Go fig hahaha ) And im not about to diassemble my cfi without a cam to take pic of evrey thing i do incase i forget... I guess i could draw it all out but i might miss something.. which is No Good.


                          Uhh... Thats the only way to take are fuel injectors out??? you would think they just snap or pop right off sitting right there and all. heehehe

                          O yea. my injectors look like at some time. the engine backfired up into them and melted the tips around them off a bit.. or one of them does.. So im thinking that one want have much help geting cleaned... I will try Seafoaming the shit out of it though today :-D

                          And if i can find some chevron tecron fuel injector cleaner ill use 4 bottoles of that in the tank..
                          Would sea foam work just as well..

                          And how bad you fellers reckon this stuff is on are fuel pumps? Humm

                            It's really not that complex taking the CFI unit apart. Just take it off the engine and take the screws out of the bottom (where the CFI unit mounts to the intake manifold). The two halves should come apart and the injectors should come loose. There might be a bit more to it than that; I'm just going on memory here. Either way, it's not really too bad. You can handle it.

                              O really? It's not like a carb then with 1000 little parts coming loose as you take it apart?
