changing injector o-rings

[strokin_97]

i was wondering what signs would indicate that i need to change these and how hard are these to change? any help would be appreciated. thanks

their not that hard to change. Just be careful not to damage the electrical connections under the valve cover like I did. Their is an exellent thread on how to change out injectors.

[strokin_97]

how would i go about finding that thread?

a sign is, lots of smoke on cold starts. poor fuel milliage, and fuel in the oil

ok thank you

^ Agree'd... I'm going through the same issue but I also have a bad knock associated with that. I know I need to replace my injectors, but I also need to determine why they failed - more the likely low fuel pressure.

I need them., but luckly i dont have a knock.. thank god. I think the injectors are still wokin, but the orings gotta be shot due to my 10mpgs

Do remember, anything you try on your truck is on you - following a DIY this involved is entirely at your own risk.

It's a fortunate failure... I was going to do them - but during the summer.

My truck will be mucho faster

Ah. I am trying to wait for spring/summer too!!! i hope this doesnt bit me in the a$$ too! I hsold my edge to pay of gauges and programing to get the injectors. so I just got the gauges. but being stupid i spent the chip money on the 07 conversion. so now im waiting a week to buy the chip, so I am loooking at early spring. plus i plow and cant have my truck apart when snows coming
