ok well i went to autozone and i picked up a can of throttle body spary i clean the throttle and it was dirty as ***. i was wondering if i could take the throttle off to clean it. also do they make bigger throttle bodies for a maxima. also i would like to know (way off topic) what does an intercooler do?

 

U can take it off to clean if you want. Intercoolers cool the incomming air of boosted cars.
