My truck seems to run a little rough on a cold start. It's not too cold here yet though, still Summer obviously. It usually idles about 1400-1700 RPM upon start up and then gradually decreases to normal idle speed (about 750-800 RPM) as the engine warms up more and more. Now it starts and runs rough at about 1200 RPM's but if I give it a little gas when I notice it running rough it seems to correct the problem only it doesn't seem to idle much more. The engine pulls strong like normal and there isn't any issues at operating temperature. It almost makes me wonder if there is a loose spark plug wire or something and it's running on 5 cylinders for a while or if it's the cold start injector? What do you think?

sounds like the coldstart injector
