Vacuum leak, TPS problem, low compression, or you just need to adjust idle speed up. It will never idle properly at 400 RPM.

got a wideband if so what afr try to idle it up first and see if it clears up if not check injector clips ad see if one of the primaries are off . you can also take a spare cas and plug it up with fuel pump jumper wire in and spin the cas to see if u hear multiple clicks which will be the injectors firing i had a similar prob and one of my inj. wires came loose in the harness and it took monthes to find the prob which blew my new turbo
