01 injector change

[the witchdoctor]

I started my truck yesterday morning, at it had a miss on what I think is one cylinder. When i started down the road, the miss cleared up, and was fine. I have noticed in the short period I have owned it (about a month), that even with the warm weather, it seems to be hard to start sometimes, especially the first time it is cranked that day. It has 240 on the clock, not for sure on Maintenance before I got it. It does have a hypertech programmer with it, but it did it after I pulled what program was on it when I bought it to return to stock. I then put the stage 2 program back on it with same results. I know this programmer is not a good one, and plan on going to a chip as soon as i get my gauges installed this weekend. I am very mechanically inclined, so how hard are injectors to change? It doesn't appear to be putting fuel in the oil at this time.

Mine did the same thing I had a buddy of mine that ownes a shop hooked it up to the computer and did a contribution test and number 8 injector was not keeping up so I changed the number 8 injector very easy to do in my opinion just make sure you try to vacuum all the oil out of the cylinder when the injector is out,but that fixed my problem I will eventuall change them all when I have some extra money .

Since this thread is on injectors, my '96 has over 250,000. Runs good but when cold lots of gray smoke. Glow plugs are good. Will new injector help with cold starting. Seems like a lot of miles on the injectors but I don't want to waste money if it won't reduce smoke, improve mileage, etc.
