Injector Question
I have a 99.5 crew with 215K miles. I figure at some point the injectors will start to go, but crossing my fingers........i read an article about the #8 cylinder injector causing hard starts and rough idlling......is this right or was that in the older models?
Thanks!
Thanks!

I definitely have one. We have an '01 at the base that had a standard injector put in place and it sounds SOOOO much better. Of course, it has the requisite oil leak at the I/C boots, and all that, though. 
But now all I can hear is that d@mn "clack...clack...clack..." every time #8 fires.

My '02 was built in Aug of '01. I guess that means it had the LL added later because when I listen to mine compared to the '01 at the base, I can definitely hear the little ball-pein hammer every time #8 hits, especially when first started. I guess I'll go ahead and pull the VC to make sure before spending the $$$, but by ear there's no doubt.

So the question about rough idlling was never answered. Also i had that #8 start acting poorley like a week after i bought my truck after i replaced it with a new LL it ran a little rougher on cold starts almost a miss and then quieted down after about 15 sec of running.

I never had a rough idle, just a noisier one when cold. I don't think it should cause a rough idle -- it was put in to keep the cackle down a bit. You would think that a standard AD in #8 fighting with #6 for fuel could cause a rough idle, but I've never heard that one. Now that I have it cross-connected, it should be smooth as a babies butt, but I still hear that dang "TINK-TINK-TINK...." because of it. That's the only reason why I want to ditch it to see what happens.
Of course, now that I'm seriously considering the Stage 1 single-shots, this whole plan might go out the window. Why spend $130 on one injector if I can get a whole set of 8 for a little over $600??
I've just made up a list of things to do this weekend (most of it in the garage
). Yanking the VC to get eyes on my #8 is one of them.

WonderDonkey, the rough idle could be caused by air in the system( that is also a big part of the cackle issue) from your QC fittings on your fuel tank. it could also be caused by a problem with the IPR, or IPC.
