I just swapped out my intake (stock 1990 5.0 w/exhaust) for another stock unit that I ported out pretty good. I got everything clean and sealed up good installing it, however when I was disassembling the old one I messed up a couple injectors. I busted the little plastic caps around the spray nozzle cause they were pretty hard to get out, but I had an old set of the same size injectors that look slightly different but same color so I used 2 of them. After I got it back together it started right up with no leaks, but runs rough like it has a miss. The plugs are good and are all getting spark but look a little lean especially on the passenger side where I hear a ticking noise. I can also hear a ticking at the end of the exhaust and I think I can feel it in an injector but could be a vibration from the motor. It runs weak but idles pretty good (doesn't jump around), vacuum lines are all hooked up, timing is at 16* and TPS is set at.98. Is there anyway to test injectors? I cleaned them all with some brake-kleen and put a small amount of vaseline in the o-rings. I kind of need to get it going by tomorrow for work ao any info would help a lot.
