Ok my friends car is having a problem. Its a 97RS-T with a custom kit. IT has the missing link version 2 for a fcd. Ok heres the problem when u start the car it wants to die. It stutters and then shuts off, but if u give it gas at first it will start up and be ok. it then idle fine but if u dont it will die on u. Also it feels like there is fuel cut around 4. It kind of smells rich and was back firing when he shifted. We took it to get the codes checked there were 5 but it could only read one for some reason the codes that we know of are 1) Egr "we removed it and put on blocking plates) 2) Evap system also removed, 3) No rear oxygen sensor. i dont know what the others r and the maching around here to test r messed up *It started when he had the black box from my star kit on it but we replaced that with the missing link 2 * New plugs r in it gaped at .035 tryed factory and one range colder seemed to run better with factory * plugs wires r not that old either less then 5,000 on them * tryed a new map sensor but still the same thing didnt help it any. Car is equiped with a safc but there has been no tunning done with it and connections r soldered in. Also dont know if u will need this but it has a walboro 255 with a vortec fmu with the 12:1 disc and stock injectors thanks any help would be great
