hey guys im swappin my 00 civic dx (used to have an LS) to a stock 96 dx sohc motor.. i am using a 99-00 dx harness which i plugged up everything except the o2 and intake air temp sensor.. i connected the orange wire from my iacv sensor straight to the ecu and the code for the iacv went away.. im using a p2t ecu because thats the only ecu i have for the moment. i started the car today and it kept on idling from 2000 rpm to 3000 rpm.. then as i give it a little gas, the motor will bog and die.. please if u can, help me out..

check and see if the ecu ground is screwed on tight,last week when changing my engine harness i left it loose not know the car started but when i gave it gas it bogged and died it wont hurt trying.

Look for a disconnected vacuum hose and check the ignition timing with a timing gun.

alright will do.. my throttle body is suckin in air like crazy.. that could be a problem.. thanks

WeAk_Cx

alright i've checked and theres no vacuum hoses unplugged.. the ground is good for the harness and theres nothing else i can think of.. it starts up fine but then it idles and everytime i step on the gas pedal, the motor will die.. i have one o2 thats not connected and the intake sensor isnt connected as well.. but i dont think that can be the problem... only codes that are comin out are those 2.. please help me find out whats wrong with my car..

You should install and connect the IAT sensor.

Have you checked the ignition timing?

WeAk_Cx

yea i dont really know much about motors... can u send me a thread or something to do that?

WeAk_Cx

hold up thats the sensor that goes on the intake right?

The car will run like extreme *** if you don't have the IAT sensor connected.

WeAk_Cx

alright thanks. i gotta find an intake for this thing lol..

ok so im using a 99-00 dx harness with for a stock 96 dx motor.. there seems to only be one o2 sensor plug on the harness which is connected to the cat o2... does anybody know which pins i can just wire up the o2 sensor from the exhaust manifold directly to my ecu?? and my car keeps on idling frm 1000-2500 constantly.. when i gas it it bogs too..

WeAk_Cx

ttt need some adivices...

WeAk_Cx

how do i connect this sensor? theres no plug on my engine harness for the iac sensor.. the code 14 IAC (EACV) - idle air control valve..
