That pos fast idle threw p0505 which is idle air control malfunction. So like many or some of you I went and bought a China iacv off of Amazon. Replaced it and it idled even worst. Put the original back on and it idled slightly better than with the new one. Idle still surged from 11-1400 rpm. No vacuum leaks and coolant is bled. So finally came across an article on how to diagnose if the fast idle valve is bad. You basically remove intake tube and inside the throttle body there is a hole up top for the iacv and bottom hole for the fast idle valve. When the car is cold out your finger over the lower hole, you should feel suction. When the car is warmed up there should no longer be any suction from that lower hole. If your car is still surging, put your finger over the lower hole again. If the idle stops surging and goes back to normal then the fast idle valve is stuck open, allowing air into the intake even when it’s warmed up causing the surge. Removed the valve and you guessed it, the oring was loose. I just tighten it. Didn’t clean it or anything. Put it back and the idle was perfect. No more CEL.

Just so people are aware if they come by. This only works on older Hondas/Acuras. Anything 2003 and up does not have a fast idle valve. As anything newer than 2003 is fly by wire and sensors, and controled by the computer. But decent video thank you!

Wow, you rock, You're a great mechanic. My 01 Honda Civic EX (bought new) has developed an oscillation at idle (rev up & down) when cold, usually tapping the brake stops it (idle completely normal when engine at operating temp). Either way, I've rebuilt 2 engines in the past, a 401 Riviera, and a 350 Skylark so know a little about engines, but this Honda is such a mystery to me and I'm at a loss to figure out this issue. I was very impressed with your tutorial and will definitely start with your approach. If you ever move to Santa Fe, I would definitely let you service my vehicles! Best!

I would suggest inspecting the O rings as well. One of mine was plasticized and two others were frayed. You can roll the dice on parts from a junkyard, but best of luck getting the large O ring that sits on top of the "air side" (the first end that he opens in the video). In the end, I replaced my frayed O rings with ones from a junkyard and had to order the large round one from a Honda dealership.

Pro tip, use something plastic and flat to turn the FIFV so you remove the chance of chipping it. Less stress trying to be super delicate with it when you turn as a metal screw driver can really mess it up with no effort.

Excellent tip! It solved the idling problem on my Civic 93! Did realized the reason the plastic cap losens out.... the O-ring of the plastic cap, next to the thread, with time hardens up (looses friction with aluminum body) and with engine vibration allows to unscrew eventually again. Replace with a NEW O-ring!

The only way a motor can surge is with air coming in, you probably have a big intake manifold leak. They spraying break cleaner on any possible leak areas. Common leaks are found on vacuum ports, or throttle body gasket and interior o rings, I’ve even seen the break booster leak. Just check everything

Try starting the car , then unplugging the idle controll and see if it’s the same. The computer is programmed to control your idle up higher with a colder coolant temp. So it’s possible you have a bad temp sensor. But try the unplug thing and get back to me.

Does this method work on 2005 Honda Accord?

My 1992 honda accord idles around 650-700 rpm, but it almost dies when I put it in drive or reverse. Thoughts? I already cleaned iacv and adjust this fast iacv

Any updates? Did you fix it? Have the same issue on my 91, I’m planning to replace iacv this weekend

Hey mate I have a b16a2 cleaned IACV and just now did this and nothing has helped, have anything else it could be?

Any vacuum leak will do it, smoke test or “breAk clean test, to make sure there’s no leaks. Also if your tps is out of calibration it can cause it as well.

I have an "88 accord with 54K miles. Idles terrible when in drive, idle goes down if I put it in neutral. Does this sound like the problem you addressed here? TX, Paul
@GearheadsAutofab5 жыл бұрын
No that sounds like a different problem, how is the idle ? Is is surging or low or like in even ?

Just picked up a 97 integra, b18b1, no fitv , cleaned IAC, tb, and tps, was idling around 1300 before I cleaned tb, now it's at almost 2000. I'm lost and getting aggravated

Sounds like you have a air leak in the manifold. Let it idle and spray break clean any where you think it might be leaking, if idle changes when you spray a area look closer at that spot for a leak. If this test didn’t reviel any leaks than make sure the throttle blade it self is not stuck open too far. There is also a idle set screw that may need to be adjusted or could have fallen out as well.

Wait you said this valve is coolant controlled? I ask because while doing a job on my b18b1 i nicked a coolant hose that was attached to the intake somewhere so i ended up substituting that hose with one i think might be a bit bigger then what was on it. Would thay cause this valve to go haywire as well and cause high idle?
@GearheadsAutofab11 ай бұрын
Yes there’s like a thermostat in there that closes off the air way as it gets hot. But changing the hose size will mot effect it. But if there’s any air in your system it tends to get trapped in those lines and can cause idle surge .

@@GearheadsAutofabthanks a lot for responding dude. That would make sense as the job I did was a head gasket so I had to take a lot of things apart. So you think air could of gotten into the system when I had all the lines and radiator take. Off? It's a weird idle issue that I've never seen before. On first start up it idles very high but as I drive it, it's fine until I switch into neutral to stop and then it goes back up into a high rpm and once I come to a complete stop the idle will drop to normal speed. Then sometimes (not every time) after driving for a while and I come to a complete stop my idle will drop drastically to like 500rpm and sometimes it will even stall out. And when I turn on my AC it keeps the idle up to a simi normal level. It's the weirdest idle problem I have ever seen.

If you buy an old Honda, I just did just change your IAC valve, your fast idle valve and your EGR valve. A couple other parts should be changed as well too. 30 years old Just change them.

95 Del Sol running almost perfect, great response, slightly high idle after cleaning the Map Sensor and throttle plate... I noticed when I stop at a stop sign or go to park the idle slightly goes up and down a few times then settles. I also notice if I turn a light on our press on the breaks or raise or lower the windows it also settles immediately. Is this normal?
@GearheadsAutofab3 жыл бұрын
Well the brakes take vacuum from the manifold so it would bring the idle down just slightly and the windows take electric load from the alternator the can change things slightly. However it’s should compensate for that in the computer. Do you still have a small issue some where. Either a slight intake manifold leak or bad fast idle valve.

@@GearheadsAutofab I learned from another video to disconnect the battery for 30 minutes to reset the computer. That definitely slowed down the idle.... About 980 rpm right now with a very slight up and down surge only after driving for a while then stopping. And it only lasts for a few to 5 surges then stops by itself. And sometimes it doesn't do it at all. I am going to buy a gasket for the FITV, clean it and make sure it's tightened. I tightened it about 2 1/2 years ago and it helped a lot too. I have a feeling that's what's causing this.... So we'll see. Both easy fixes... I cleaned the AICV again yesterday. I may replace that if these things don't work. And check for bubbles in Radiator etc... Thanks for the help!
