car having problems....help help

phatboi · Post by **phatboi** » February 14, 2005

wellz i just finish my swap and like yeah its throwin some codes out....

10 - IAT - intake air temperature sensor
14 - IAC (EACV) - idle air control valve
41 - Primary oxygen sensor heater
54 - CKF - crank fluctuation sensor
65 - Secondary oxygen sensor heater

wellz yeah i noe the code 54 is because i dont have a sensor plug for the oil pump....
and 65 is going to be taken care of like in couple days....

but i have a question behind the stock ls intake mani there is a plug and that plug has 2 wires... but im using my stock civic harness and like that plug that goes there it has 3 wires... and i dont noe how to convert that... any help on any one of those codes would be GREATLY APPRECIATED.... thanks in advance

its in my 98 civic hatch dx and the motor is a 94 integra ls

yes thats the IAC valve...because your car is a dx it has a rotary IAC which uses three wires, the same as all automatics...the integra and all other manuels use two wires i'm not positive on how to convert that but which ecu are you running...hopefully the ls, i would think it would work okay then but i would search on honda-tech, or rewire that plug to your ecu. as for the IAT i dont know what could be causing that maybe the sensor is just bad

are you running an obd1 or obd2 ecu and do you have the ls wiring harness?

currently im running the stock ecu because im out of funds to buy one.... and im running a obd2 and i do have the ls harness....

yeah thats why its doing that, your car shouldnt even start does it? it should like start and die right away, wont stay running at all...you need that ls ecu. i do not think you need the ls harness i just thought of that because i figured you had the ls ecu in there. get that shit in there and let us know how it runs

anything else you cant figure out?

Did you swap distributors, splice injector wires, etc? You also have to swap a few pins on the harness.

an obd2 ecu is going to flip shit on an obd1 motor.

cant you just get the shit from an obd1 car and replace it with obd2? or is that impossible?

wellz the injectors are all the same both 240cc or something like that, so i just used the d16 and it starts fine but runs funny.... like the dizzy just cut off the plug off the d16 and ls and swap plugs.... same with alternator.... but that plug in the back of the intake mani... is getting to me and my friend say that i need the male plug o2 sensor....

wellz tonight im going to steal my friends ecu to see if its going to run better with that but yeah ill keep everybody informed on it
