    ok i swapped an obd1 b16 into my si! used a boomslang harness converter and pr3 ecu.'''' the motor will start on occasion and run eratically jumping rpm revs!and other times it will idle smoothly. but when it starts to run erraticaly it will eventually after dyeing and restarting several times. get to the point where it wont start at all! like it is cutting the main relay out,, i have gone through seven different main relays. and it gets to a point to where it seens like the relay is shot!also when it is running rough the main relay chatters''''''any help would be greatly appreciated! i have checked and rechecked wireing!!!!! all seems to be wired correct. what can be the problem HELP PLEASE? ALSO THE MAIN RELAYS ARE NOT GOING TO HELL BECAUSE AT ONE POINT THE RELAY SEEMS LIKE IT DOES NOT WORK. so i swap in an old relay and it will statrt the car! the pr3 ecu has been socketed and chipped. was this way when i got it from japan.

    vacume has also been gone through over and over! my boy wants me to bring it too his shop. but i am thinking it gotta be something simple'' and i would hate to pay shop rates for trouble shooting that could be costly!

    iratic idling could be the water temp sensor, but more than likely it'd be throwing a cel. but not if it's still "within parameters".
