This is a ob2 ka24de-t motor a plan on buying but would like to figure out whats wrong with it first.It idles at 2000 and was told it only started doing that after it was tuned at alamo autosports and it was probably a vacuum issue... I searched around a bit and found that it could be vacuum leak,iac stuck open/closed, idle screw adjustment and timing.This also uses a map instead maf, curious on what you guy's think about this.

here is a list of the parts installed-

Bc cams 264
Bc springs an retainers
AEM EMS -its tuned on 10 or 11 psi by alamo autosport
740cc Hks fuel injectors
Peak boost top mount manifold down pipe and dump tube
Greddy bov
Tial wastgate 38mm
Garrtte gt35r
intercooler pipping
Ka24de bock bored .20 over with eagle rods and wiseco pistons
