im haveing some idel problems it will idel at 800 for a lil bit then once warm it will surging to about 1500rpms any ideas on wut it is i have cheacked all the sensors and for vacum leaks and thos r fine now i dont have the knock sensor or the plug that id directl under the intke manifold on yet would that be the problem any help would be awsome

 

Do you have any CELs? Have you cleaned your IACV? Try taking off your throttle body and cleaning all the orifices with carb cleaner. Don't forget to reset your ECU after as well!

 

wut r CELs and yes i took the IACV off n cleaned it off with carb cleaner....and i reached in with a rag n carb cleaner and cleaned it the best i could with out taing it off and its pritty clean......i just took it out of a car and it was running fine in it and now im just havong little problems....also wut is the plug rght under the intake manifold its a 2 wire plug conects directly under the manifold

 

CEL is a Check Engine Light. I -think- that 2 wire plug could be your TPS. Is it on the throttle body or under the IACV? Your IACV has a plug on it too =P make sure that's plugged in!

 

its right next to the block right beside the knock sensor and the check engine light is my knock sensor i have to wire those 2 plugs in to the ecu still but i dont know wut the plug is im asking u abt is it the IAB

 

Not entirely sure on this one but I don't think knock sensors are on OBD1 motors. Are you using an OBD2 ECU and harness? What year is your car?

 

im using a jdm b18c in an 93 civic hb si with a obd1 ecu
and im getting a code 23

 

B16As and B18Cs have knock sensors, B18As and B18Bs do not, regardless of OBD version.

if you are using a P72 (GS-R) or a P30 (B16A) ECU you will need to wire in a knock sensor Alternatively you can use a chipped P28.

 

wut is the 2 wire plug that connects close to the block directly under the intake manifold

 

Pics of said connector would be really helpful, or at least the wire colors going to the connector. As a guess knock sensot, thats all I can think of in the location that uses a 2 wire plug.

 

the knock sensor is at the block the one im talkn about has a pink wire unno wut color the other one is but i think its the IAB plub but not sure

 

Again pics would really help here. pink/blue and yellow/black is for the IAB solenoid.

 

i got a great a feeling that harness can be the anwser to ur question have u tried plugin that harness right under the intake manifold???? does ur vtec kick in???

 

yes the vtech kicks in i dont have the knock sensor or iab silonoid run to the ecu yet im doing that today i will let yall know the outcome and hopfully it helps pluging them in...thanks for all the help guys
