High idle / boggs at startup

[DsmKid98GST]

I recently installed a port and polised 2g throttle body. It is identical to my stock just... port and polished . I'm using the stock TPS and ISC sensors and the person who supplied the P&P job gave me new gaskets also.

I'm getting high idle at 1500 rpms. At times it will idle around 1000-1100 rpm but after it's warmed up it's back up to 1500 rpm. I turned the idle screw to where it was idling at 1000 while i sat in the driveway. After and while driving it went back up to 1500.

When I start the car up it bogs down and then surges up to 1300ish and then down to 900 rmps (twice).

Any tips or reasons to why it will be doing this do tell

Thanks

I believe you have to ground it whenever you move the screw around.

Could you be more specific please?
