I'm trying to remove the throttle body on my 99RXAWD. I've removed the two nuts from the top flange and the one behind the cruise control bracket. I can't see or feel another bolt but it feels like there's still one holding it on. Any advice? Are there 3 or 4 nuts holding it on?
Thanks,
Baetke

Thanks Hypervish & Salim,
The link hypervish sent me gave me the information I needed. I would have never found those two bolts by myself. I finally got them out so I could remove the throttle body so I could remove the IACV and thoroughly clean and lube it. That solved a low and rough idle rpm problem I was having.
Thanks again!

Lube does not seem like a good idea. Maybe there is a right lube ... motorcycle shop can be a good resource.

The gumming happens due to oil and fuel vapors and a disassembly at 100k miles and a squirt of cleaner every 50k should be enough.
