thats great info, thanks. is this something i could do on my own? where is the throttle bore located?

[clogher]

not sure but if you spray carb cleaner in the throttle body with the hose to the air intake off it should clean it i am not sure about any sensors you may hit with the carb cleaner or where not to spray this is the in take so carb cleaner should not damage anything in there

I have a 2007 Uplander and the idle is a little rough .

A buddy GM mechanic that works at a local dealer , said it is due to the Variable timing.
