car wont idle when started...swapped EK
 

i got a '00 LS motor in my 97 EX civic. everything went cool with the swap. when i tried to start it at first i couldnt get it to start without holding down the gas slightly for around 10secs then it will idle. at first i thought it was because i didnt have the exhaust hooked up yet.

well i hooked up the exhaust, and i still have the same problem. when i start it, it will either start and idle so low that it almost stalls, or will stall unless i give it gas for around 10secs. after that, itll run fine until i cut it off. then if i crank it back up, itll crank up and idle ok, although still somewhat low (500rpm or so).

i was also driving last night and threw a code 14 (IACV). this is on a '00 LS motor with only 48xxx on it. i took it off and cleaned it with carb cleaner and im letting it dry now. i just dont get what my problem is since the car idles fine after it runs for around 10 secs with the gas slightly pushed in. help me out HT!!!

oh yea, on a side note, could my throttle cable have something to do with this?? im using the '97 civic ex cable on the modified LS bracket. it doesnt appear to have a ton of slack in it or nothing....maybe it needs slight adjustment?? stumped http://images.honda-tech.com/set1//smile/emcrook.gif

if the cable doesnt work you can try turning the little screw thats on the throttle body with a flat tipped screw driver. and the car should be on so u know if your turning it the right way.

i dont think that has anything to do with it. if that was the case, it would never idle. it does idle ok after it warms up

I did the same swap in my 98 EK and it does the exact same thing. It idles low and it gives me trouble in the morning when i go to start it. But once it worms up it runs good. If you find out what the problem is Let Me Know
Good Luck

you have to switch a wire on the A connector at the ECU for the IAC. im not sure of the pins maybe someone can help you out its been a while for me. i think a 12 to 14 maybe but dont quote me on that

thats only if ur using a DX/CX harness. im using the EX harness and its all plug and play

check dizzy, plugs, plug wires......simple shit first, lets eliminate shit before we jump to conclusions....what ecu u usin?

went to my boy's shop and he double checked the timing. it was 1 degree off and he set the timing to 16, dizzy is fine, plugs and wires are brand new. using the stock p75 ecu. im not a newbie, i have checked all of the small shit first.

he used his obd2 scanner tool to check for everything. IACV code came right back so i need to take it off completely this time and give it a more thorough cleaning. no other codes. running temp is fine, idle is at 750rpm. only thing we found wrong was that my throttle is sticking lightly and holding it open 9%. he said that may be why it doesnt want to idle in the morning cuz its thowing 9% more fuel in the chamber when the car is on the cold circuit mode and is most likely bogging it down to where it cant idle until i open it up and let more air in.

my question to HT, is there a FITV on a '00 LS motor?? if so, then maybe that might be part of the problem too because my motor doesnt start up higher rpm then go down as the car warms up.

gonna spray the throttle plate as well to clean it thoroughly and stop the sticking problem. other than that...i dunno.
