i have a 2002 chevy S10 blazer w/ 4.3l engine. my truck does not have the sticker of the vacuum diagram under the hood. i have been looking for 2 days straight and can't find it. can someone please help me out w/ this. and i really don't want to go to the dealer.
sorry, my blazer is 2wd and my truck is throwing codes 171 and 174 for the O2 senser. and on the drive side valve cover there is a vacuum hose coming out form the PCV and going to the drive side fender, just to see were it goes and my cruise control is electric. i have tired searching and all i find is the ones for 94 and older.
i went and looked at my truck and the diagrams and it doesn't show the hose that i pluged w/ a screw. there are 2 hoses that come from the PCV, i took some pics of it and the hose is the one w/ the red arrows. here are the pics.
