[V8] throttle linkage tips

[Dave Head]

I'm having throttle butterflies or linkage sticking at various RPMs. I 
cleaned the idle control motor today, but that wasn't it - after 
removing the air filter box, I got it to release. It moves and returns 
cleanly, so tomorrow I'll pull the front off and try cleaning the 
butterflies
Where exactly are the linkage bearings located? Does the intake have to 
come off to replace them? Are any of them 'lubeable' with like a white 
lithium spray?
