This isn't all that hard, but I've done tons of them. You have to remove the whole intake plenum assembly first. I don't mean the intake manifold, only the top part. You have to take all the air cleaner duct work off, unplug all the appropriate sensors, disconnect the throttle cables, take off the vortec plate, and disconnect a couple of vacuum hoses as well as the brake vacuum hose at the rear. Although you can't disconnect the brake hose until you remove all the plenum bolts on the plenum and kind of lift it a little bit. There are a couple of hidden bolts so get them all. It will not be stuck at all. Lift the whole plenum out of there. The CPI is now accessible. You have to remove the fuel inlet and return lines, and then disconnect the quick connections on the injectors at the base of the intake and wiggle the whole thing out. Normally, most of the plastic clips break. So replacing one turns into six. I would recommend doing that anyways as the one you replace will have an un-obstructed flow and the other five will be slightly restricted. Just look at the conditions inside of the intake area to see what I mean, but that's your call. Good luck.

since you have to take it all apart anyway--do them all at one time--saves money when another might need replacement in 6 months
