Hey guys I installed some new injectors in my truck and am having some issues. The first time I started it up it was good, but the second time I fired it up it started to have a miss. I did a buzz test and they all sounded good, so I did a cylinder contribution test and 6 and 8 failed. So I pulled the injectors back out and everything looked good checked connections. So I put them back in and the miss went away, so the next morning I go to pull the truck out and the miss comes back. So I run the cylinder contribution test and now 1 and 3 failed. Just wondering what the heck could be going on. Any help would be awesome.
