pulled the SAFC harness out and set all "OEM" ECU wires where they go...

i pulled the ECU codes, and it gave me error code 13, or coolant temp sensor... which i'm not sure would give me a bad idle....

also, as the engine was running, i disconnected the o2 sensor and nothing happened....

i reset the ECU 5 long lights, 5 short lights, and it still skips/stutters a bit at idle.... and take a bit to crank up.... also when i do crank it, it will fire, i stop turning the key and it immediatly cuts off... like it wants to start, but doesn't... i do that a couple time and it fires up and runs....

any insight???
