Hello everyone, I recently installed an engine in my 94 accord, all is great except for the idle surge. I have tried everything in order to fix this. I've just been studying the way the system works, because as you all know, the more you understand the more you can fix, the farthest I have come, is that the iacv is in fact working, but something else is factoring in to the problem and throwing it off! I'm truly boggled by this, can anyone help me run through everything that factors into the actions of the idle air control valve?
Iacv is clean, and has been swapped out with four different ones, the fitvalve is good and adjusted properly, no air in the coolant system. I have bled it after every disconnection (numerous times) under heavy, or normal driving conditions (drive or reverse) it operates great and even idles spotlessly. Only when it is under minimal load is when it surges, up and down, and sometimes sits still a higher than normal rpm range.
So, I checked the thread you linked, everyone says it worked.
In the morning I am going to pull the whole throttle body, and ensure everything is clean and sealed properly. I will let you know how I turn out.
I've been fighting this battle since I installed this engine, and have swapped all the sensors from the old one, one at a time.
The issue has made me look like a fool lol
Could the ect sensor be faulty and causing this problem?
The change rises to NORMAL OPERATING TEMP then stays, could the resistance in the sensor somehow come to a halt in change?
I have never come across that situation but could it be possible?
agreed Ghost, I tested my ect sensor, it's good. I just got back in.... as far as I can tell the idle situation is resolved. the base idle was a little off Holmes. I adjusted that as well as I could.
But the main cause I believe was the throttle cables being too tight... Not so much my main pedal cable, but the cc cable was very misadjusted; so when I would press the gas, the throttle would not come all the way back to it's original position...
Does this all make pretty good sense?
Thanks for all the help btw. I Really appreciate the feedback.
