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?

thankx

 

do you have any codes?:

 

I haven't had the chance to check that yet, but I will.

 

plug in the map sensor plug or iavc connection in the back of the IM?

 

i'll give it a try,
wish me luck
thanks

 

you are in limp mode. if you just got a conversion harness then i dont think that means vtec , not vtech, is wired up and your knock sensor isnt wired up, so hard wire those into the p2p and you will be all set. also you have to wired up components from your intake manifold

 

this is true, I do not have v-tech right now.
Where is the knock sensor?
what do you mean,
"also you have to wired up components from your intake manifold"

 

You need to search for mini-me wiring quickly!!!

I also added to this same post, but in the Tech forum. Check it out for IACV issue

 

where would I find the mini-me wiring ?

Any help would help.

 

well, I haven't had the time to do anything yet, the snow came and motivation left.
so I am still waiting, I think I will have it under control, but if I don't, I'll come back here to seek more knowledge.
thanks for all your help.
