Disconnect the Y-hose from the throttle body, remove the brake booster vacuum hose from The brake booster itself, not form the UIM. There is a little plastic vacuum line on the brake booster hose itself that just pulls off. I think that's all the vacuum lines for an N/A. Take your time on the fuel injectors and rail. I sprayed some PB Blaster into where the o-rings sit to lube them up a bit. Helped a lot.
