OK my car has been acting weird lately. It Sits at 2k-24k RPM's and i dont know why. the only thing i can think of is that its my IAC. the throttle cable isnt too tight. Checked manifold for leaks. all sensors are working. no codes are being thrown. Im puzzled.

Wish i could help.. just wanted to say.. love the driving while filming..

 

mines is doing the same... i dont know whether its the manifold or the TB...its causing it to idle real high. mines is throwing a code 10 which is the IACV but i switched to a working one, and even installed the old on my buddys car and it works..

still have CEL and car still idles real bad... dunno whats wrong! arghhhh!

 

well i can tell you your problem a code 10 is not IACV its your air intake temp sensor. IACV code is 14.

 

What is your TPS value? Should be .45v. Have you messed with either the idle air bypass screw or throttle plate stop screw?

Bled your coolant? We can bypass this for a second if you buy a ~350ohm resistor just to simulate the ECT on a hot motor.

Does your throttle body have a FITV? Have you tried 'fixing' it?

When you've got the high idle, if you remove the intake arm, unplug the IACV (and cover the FITV hole), where does your idle sit?

Ihad the same problem. Do a search in the CRX forum,using my screen name.Theres a link in there w/pics on how to fix these.

 

Dude i have this same damn problem but mine does a high then sometimes a real low idle like about 100 rpm when its low and about 1700 when its high. Ran a diagnostic tool and everything is functioning right. Only CEL i get is for my 2nd o2 sensor which i will fix shortly. Dude we should get in touch and figure this **** out.

 

I have no clue what my TPS value is. how do i check that? and if its wrong how do i reset it back to .45. Ill do the FITV today and see if thats it. What do u have to do to clean the IACV? is there a write up with pics any where?

 

ok i started the car and let it warm up for about 4-5 mins. i took off my intake i placed my finger over the hole in the TB towards the firewall. once i did that the idle dropped back down. so where do i go from here?

oops i guess i read the wrong code...

10 IAT - intake air temperature sensor

 

TTT new video uploaded with a lil more detail.

 

well i just got rid of my CEL, but mines still idles like your first video.....

bump for more info to fixing it

 

isnt this Honda tech? how come i am getting no tech?

 

when you coverd the hole and the idle droped doesnt that mean its a vacum leak somewhere? i remember Emerika helped me with my idle issue... if you unplug the IACV and the car doesnt die or it starts ideling correctly it is probably a vacum leak. sorry if this doesnt make sense im trying to remember from the top of my head.

 

oh.. ONE LAST THING... what year is the head you have? if you have a 99-00 b16a2 head. there is a little vacum port on the back of the Im on the drivers side that should go to the Cruise Control. if it is not plugged or coverd it will force you to idle high like you are. i bought a rubber nipple and pluged that up and it was fine.

 

im thinking it's your tps.
On the factory TPS sensor, there are 3 wires. The center wire is “regulated voltage”. At CLOSED
throttle check the voltage reading of the center wire. The reading should be between 0.36 - 0.44 volts. Rotate the sensor clockwise or counter-clockwise until the reading falls within that range. Tighten the two screws. At WOT, the reading should be between 4.50 - 4.85 volts. Make adjustments as necessary

 

what is the little adjuster screw thats on the IACV? its has a allen head on it

you should try looking at the idle screw. does it have it

 

i say the throttle fwaking cable! if the tb is open that much at idle what else can it be? do u have a gsr tb wire? if not try that...its more loose

 

If you take your FITV off the bottom of the throttle body and make a gasket to go between that and the throttle body that covers the whole area it will fix your problem. You might want to connect the coolant lines together to bypass it all together as well. Otherwise you will have to replace the FITV.

 

whenever you figure out how to solve this problem please inform us. I have the same problem but its not that extreme.
