Throttle body idle question

[eggo3564]

Hi Guys,

This is my first post here. Ive just put a 70mm throttle body into my car and now when it in park the idle doesnt hold steady and dips. does this mean that the car will need a tune to fix this or did the install go wrong?

Any help would be appreciated.

Thanks

try reading Cheap6's post .. may help .

base idle

edit: please dis-reguard that as the vr & vs set-ups are a bit different . crude method = try turning the throttle stop screw in a quarter of a turn .
