so i have been having issues, with my idle, and my throttle plate sticking, and not sure if its the plate, or the spring, but i was gonna just grab a new one... i was looking at upgrading to a throttle body with a bigger bore... my question is if i go for a 68mm, will i have any issuse with my car running too lean since there will be more air coming in, or does the computer compensate? and will i have issues not running a fitv since there is no fitv port? got a y7/y8 mini me, just intake, and exhaust

No, but your throttle response will suffer greatly.

Remove the TB, spray brake clean or w/e in there, clean it all out with an old toothbrush and reinstall with a new gasket. See what happens. There is probably oil vapor build up causing it to stick.

also, if anytime in the future if you decide to upgrade to 68mm, you need to bore the intake mani to 68mm as well so you dont disrupt airflow

ok so I picked up a 68mm throttle body, and because my car is a 93 LX, it has the MAP sensor on the firewall, and there is what I think is a vaccuum line coming from the bottom of the sensor to a port on the throttle body.... what should I do about this vaccuum line because my new TB doesnt have a port for it? should I just tap into my intake somewhere? and the throttle body I got looks like it doesnt hav an idle adjustment screw... do I adjust idel with the screw under where the throttle cable attaches?
