Anyone has a link or image of the drivers side of the I6? Just finished my motor swap and putting it all back together, but need to make sure all wires are going to the right place.
In particular, there is a vacuum looking part that is just in front of the starter that seems like a hose should be running to it, but I can not find the hose or where it comes from...
HELP!

Is it #13 in this picture? If so, they say it's a PCV hose:

I used this site,
http://compnine.com/index.php?s=1&catcode=56S&year=2002&modelcode=S&modelid=7131&makecode=LC
What I think your talking about is the EVAP System,, a little plastic valve with a electrical plug coming from it and two plastic hoses. I didn't take mine apart so it went back together pretty easy,, once you get all the fuel lines hooked up the two lines that are left go to that plastic valve.
Hope this helps:thumbsup:
Part number "4" hooks up to hose number "5" and "1"

How come the pics in my post keep changing?!?!:weird:
alldatadiy.com is a subscription service, and the link you had might not have been directly to the image, but a search result. They might not allow or encourage deep linking to their images, since then they're accessible by non-subscribers. You need to rehost them somewhere you control. Or here on trailvoy as an attachment.
I've seen this effect taken to extremes by some "adult" sites, where you can view an image, but if you link to it, and a sufficient number of folks look at it from that link with a referrer tag, (such as in the Platinum section here), the site is automatically setup to replace the image with another one of their choice. :hissy: Their choice is usually icky or horrifying.

Got it. I usually save the pics to my computer first but it was too early in the morning to think straight. I'll try to repost, thanks Roadie. :thumbsup:

'02 envoy cylinder ID
Hello everyone, first time here. Not even sure I am doing this right but...I just bought the vehicle, 112K miles, and it just started running very poorly on and off. Did the code check thing at Advance Auto and they say i have a misfire n cylinder 3. As it is on and off I am guessing it is the coil pack, so now I need to find out which cylinder is #3, I have purchased the new coil pack, just need to know which cylinder. Any help is very much appreciated, Thanks

They're numbered from front to rear. If you just bought it, and didn't get trustworthy service records, it's time to change ALL fluids and the filters and especially the spark plugs. Only use Delco 41-103 iridiums. Especially important and often neglected is the transfer case fluid every 50K miles, not 100K. Good luck. There are MANY threads about doing the 100K maintenance items.

Thanks for the info and what I'm sure is good advice about replacing plugs and fluids. Will do all of that just to be sure. Thanks again!

My dashboard shows the comment "Low Oil Pressure" in my 2006 Chevrolet TrailBlazer LT 4X4.
Kindly help me to find out the problem, and the solution if anybody have. Many thanks...Qazi.
