I have a 1998 Civic H/b, I put a 2000 Civic EX engine in and kept the DX wiring harness. I just picked up a 2000 Civic EX computer and a harness to change OBDIIA to OBDIIB and to use the EXs full potential (along with V-Tech).
I plugged the new computer and harness in and it is doing something weird.
At idle, it pulses from 1500 to 1600 Rpms, and when I give it gas, it only goes to 5000 Rpms.
Does anyone have a solution to my problem?
Please?

it's most likely your IAC valve... your DX had a 3 wire unit. The EX manual has a 2 wire unit. So probably your DX harness is wired slightly wrong for the EX computer.

i already told you the things you have to wire up in the other post you made about the same question .. iacv, vtec solinoid, vtec pressure, knock sensor, and maybe some other stuff.. yes the old wire harness will help you because it should still have the plugs you need and the wires and all you have to do is add them in and wire them in at the computer.. compare the dx wire harness to the ex and you will see what you need to change

Mitch that would be great.
It shouldn't take that long.
I have everything, just the time thing is bad.
I have the OBD-IIB computer, and a conversion harness from Boomslang.
I also have an APEX-i VAFC to put in.
I don't have any of the little pins to re-pin the computer, if I need them.
I just need the time and the help.
How's Sunday July 31 for you?
My girlfriend is going to the shore and I am alone all day.
If that doesn't work out, I am off on Wed. and Sun.
Do you still want to go see Rob's shop sometime?
If so let me know, we could meet up and cruise over there.
Later.
Pat
