The intake manifold removal process was a big gnarly, scary mess (but I did it, so anyone can)! So many connections, so many bolts, and other stuff. I bagged and tagged everything, and recorded a lot of video, too. The folks at www.1aauto.com have some great videos, theirs are worth watching. But, like the half hour gear head shows on TV, they gloss right over some stuff that, to a newbie, is very daunting.
My 02 Tahoe throttle and cruise control are “old school” meaning, mechanically connected. I understand that newer technology allows for “drive by wire” which, I guess, is wireless throttle? Anyway, I had to disconnect mine, and for the life of me, I couldn’t figure out how because 1 A Auto skimmed right passed it. A lot of times, pros gloss right over stuff because they assume that the step is so easy that any moron could do it. Sometimes, us noobs, (or is it just me?) need that extra little help.
The throttle body is cake, but those connections for the fuel injector sensors is crazy confusing to a noob. I spent a little extra time on these in my video (and the throttle cable stuff) for that reason.
The fuel lines can be a nightmare if you don’t know (here we go again) about the retainer clips that you have to undo PRIOR to just the regular task of disconnecting them. You need a special tool to disconnect the fuel lines, but not knowing about the retainers can make this an agonizing process. I go over that part in the video, too.
Other than that, it is just the sheer quantity of stuff that disconnects from the intake that make this a hard step. I recommend bagging and tagging everything well, and taking video (my opinion that photos just are not enough) for this step.
