ok well i finally got time to get back to the car today, i reconnected the + battery teminal, got in turned the key, "vrooommm" started right up, idling very nice at like 1200, it was ice cold and i think i turned the idle up last week, but smooth. It didnt even smoke really like it did last week. i let it run a few seconds, its still not full with cooloant(since i was maybe pulling the timing cover) after like 10 seconds, i gave the gas pedal a little stab, it easily shot the tach up to 4500-4700 rpms solidly. And the SES lights is off and stayed off. so all in all i think i figured out the issue it had. apparently the ECM was bad and messed everything up since thats all i changed(other than correctly setting the base timing

) but the SES light now is fine and i dont think bad timing would have set a code 51. Tomorrow the car is getting registered and insured, then i can test it on the road and fine tune it from there.....
