Timing chain replacement

Haha, right ; >)

Okay Ken, I replace 2, 4, 6, 8 all seal on those four injectors. It did great at first, after a couple days the miss codes 302, 4, 6 and 316 came back. So I began to watch it, creating the codes ect trying to pin point what exactly and when they come on. It seems it is only on a cold start, after it has warmed up and I clear the codes, it never comes back until like the next morning or a cold start. I used the correct tools to install the seals and injectors the only difference is now, I do not get a miss code for #8.
