Yes, you have to pull the blower.
It no big deal, just remove the belt, throttle linkage, intake tube, top w/upper IC tube attached, loosen clamp on bypass hose, unplug IAC and TPS, remove the 3 retaining bolts and a few vacuum hoses. Only takes 10-15 min. Reseal the top and IC tube with Permatex orange RTV.

PS: Getting that bolt out of the fuel rail near the firewall will be much tougher.
