2G Wont idle

[MCgeemdm20]

Bought a 98 gst. has aftermarket intake, inter cooler, fuel injectors, and BOV. put brand new engine in, has no boost leaks. Runs great but will not idle at all. I have already checked the MAF and the timing/boost leak problem. also has a 6 bolt swap in it with a new CAS. just wondering if anyone has had similar problems. my next step was gonna be to change the IAC and the TPS. ALSO BOV was open to atmosphere but i recirculated it and still nothing, thanks

What do you mean by wont idle? Are you running any engine management?
If you have a Volt meter you can check the TPS and ISC.

That video is very basic but Jafro has some great easy to understand videos. Hope that helps. Also if you are running bigger injectors you are going to need some kinda of fuel management adjust the fuel trims accordingly.

maybe your throttlebody is dirty and it can`t get in idle position. so try to clean it. sometimes it is something little thing like that

Do you have idle surge or just a low/bad idle? Little more info.
