Ok, guys I swapped in 440cc injectors today, I got them in and all that but when I did it the first time, I didnt put the seals from the old injectors so there was a vaccum leak and the idle was incosistent and high due to this. Anyway I went and put the seals on and tighten down the nuts onto the studs and I did them oppositely and alternated to push the injectors down into the seals... anyway I broke the threads off the right side stud... I tightened the other 2 well and the far right injector was just barely not seated all the way into the seal, it was about 1/4th the way into the seal and the other 3 were all the way in. It still looked to be making a good seal just not pushed all the way in and everything was tight seemed ok even with just 2 nuts on. I went to start it up after adjusting the fuel maps and such in uberdata and now I have a check engine light and its running like a damn muscle car, it sounds like it's lobing... I am pretty sure one of the cylinders isn't firing for some reason.

Could that last one not being pushed completely into the seal cause the cylinder not fire? Or bring up a check engine light? Or did I break something in the install.... help! Any ideas?

 

no clue?
