o2 sensor.. u need a new one

 

check for vacuum leaks!..

 

clean TB, clean and check your IACV also check for vac leaks and you may have to ADJ the idle ... keep us posted

 

IF I HOOK UP TO A COMPUTER WILL I READ OUT ANYTHING?

 

if you have a cel....this a eg or ek ..obd1 ? obd2 ?

 

YOU LOST ME THE ECU 'S OUT OF CX BUT THE NEW MOTOR IS OUT OF A DX MY MOTOR HAD THE OIL CAP ON THE LEFT HAND SIDE AT THE BOTTOM AND THE MOTOR THAT I HAD PUT IN LOOKS LIKE ALL THE OTHER HONDA MOTORS THE I HAVE SEEN. COULD THE MOTOR BE DIFFERENT?

caps off????? you make no sense bro

 

what kind of ideas does your motor have. up and down, sounds like its bipolar..... jk id check vacum connections.

 

I'M JUST SAYING THE NEW MOTOR LOOKS ALITTLE DIFFERENT TO ME.

 

you are a nut

 

no i just think the guy that i had put in the motor sold me a different motor

 

seriously check your o2 sensor

 

like every said, check all the vacuum lines. you have a leak somewhere. guaranteed!

 

This thread is jokes.

I give FULL respect, to ANYBODY that tried helping this guy out. I personally could not decipher one sentence that this guy has typed. And when I do figure out a sentence, I still cant figure out if he's asking a question or not. The surging Idle question that I assume he's asking...is so vague that I cannot begin to help him out.

The only thing I can suggest, is a vac leak like E Gee Two has already said twice. He knows what he is talking about so please take his advice before you ignore him for a third time and confuse yourself and everyone else even further. Check to see if your MAP and TPS is switched as this can cause a CEL and sometimes a surging, erratic idle.

And when you said "IF I HOOK TO A COMPUTER WILL IT READ OUT", you can't hook your car up to a computer, however you can jump the ecu jumper to find out what the CEL codes are. Then look up the CEL codes and go from there.

But I have a strong feeling that you'll never understand what I said to you about the codes, and when I tell you to search to figure out what the codes mean...I also know that you'll never do that, so why am I wasting my time typing? I hope that I'm wrong...but I have a feeling you will not rest until someone types out for you step by step how to do each thing that everyone here reccomended. I cannot speak for everyone else, but if you don't want to search...I'm not going to do it for you.

/end rant/help.

Now my head hurts....thanks man!

 

If you have a CX ecu and DX motor, obviously you need a DX ECU.

Never heard of an O2 sensor affecting the idle. It's a vacuum leak or plugged IACV.

uh also it's the o2 sensor lmfao.... it could be either or but my money is on the o2 sensor cause every person i've ever known, when their idle is like that and they get a new o2 sensor, it goes away....

What the hell man..... yeah good thing you figured out swapping a jdm motor into a north american car dosent work! no wonder nobodys car on h-t runs right

SERIOUSLY its probably your IACV, a couple mixed up vacuum lines, a backwards check valve, or your O2 sensor.

 

the guy that put in the motor said it was a cold start sensor, he said he changed the o2 and no vac leaks but thanks for your help.

 

haha its a mystery. alot of civics do that. even mine. i just learn to live with it. or atleast untill i save up enough money to just take it to honda and let them check it out. but yea you can do all the things that they tell you here. if one thing works then it works, but if none works then let pro's take care of it i say. haha i know alot of people are gona bitch about this but owell. lets wait and see what they say.
