Sorry for the vague title not sure best way to put it. So just bought a 91 gsx from a guy who was the 2nd person to start this project. It originally was automatic and converted to manual. Bought it not running it has rebuild engine, 340 fuel pump, new turbo and larger cams and safc2 he also had a 2g maf installed and fmic. Having a hard time getting it to idle great. So since I have bought it here is what I've done. Had the ecu repaired and converted to eprom, new plugs gapped to .28, new tps, and new isc. I also swapped in freshly cleaned stock 450cc injectors. It looks like a new o2 sensor. Boost leaks have been taken care of. So not sure where else to begin. Any suggestions? It is trying to idle around 550-600 rpms. And while trying to adjust the idle I can't get it to change at all.
