When i unplug the sensor when the engine is running the idle stops bouncing around to acts normal but has CEL.

Is it bad? time to replace it? i tried cleaning the screen and no i didnt use brake cleaner =/

it has irratic idle when its plugged in, and when i press the clutch in it stalls sometimes

 

could be a vacuum leak.

make sure your throttle cable isnt adjusted too tight.

make sure the FITV (if your car has one) is functioning properly.

if you cant find a vacuum leak and the FITV isnt the cause then i have a IACV from a d15b7 and d16z6 i can sell you.

of course, you didnt say what car you have or what motor so i dont know if either of those would do you any good.

 

It's a d16z6. hondata intake manifold gasket. and b18b throttle body i dont have any leaks at all. =/ and there isnt a FITV on this one

 

i was having the same issue until recently where myc ar wouldnt idle correctly.

it wasnt the IAC or a vacuum leak.

i swapped out my skunk 2 intake manifold with 68mm TB for a stock one.

problem solved.

i think my problem lied in the throttle body.

adjust the throttle stop screw on the throttle body, its under the pulley a 7mm locknut and an allen screw

 

i tried that too, thats what i thought it was. But its weird as soon as i unplug the IACV the idle surge's stop and it idles normal

that typically means you have a vacuum leak of some sort. or the throttle plate isnt closing all the way (which is a vacuum leak)

i guess it could be that the iacv is bad as well.

i do have d16z6 iacv that i can sell you, its in good working order.

yours for $30 shipped.

 

ill mess with the throttle body some more and see how that goes. if it doesnt help ill be in touch for that valve haha
