Hi
I buy Honda Jazz 1,4 2004.
After 10 km check light on . mechanic said me that ERG is dirty and have a problem with IACV /Idle Air Control Valve /.
We changed the spark plugs, oil and all filters.
when we gathered everything, it turned out to be IACV not working.
Change it, but error still.
Are something have idea where is the problem?

Did the mechanic gave you any Errror codes?

No.
He dont give me a code.
I see with my eyes that the IACV is not open., it alwayes close

Does the car exhibit any physical symptoms? i.e. lower fuel economy, rough idle, hesitant acceleration?
The wiring in that area can be damaged where it bends 90° in the conduit, may be worth checking continuity.

You can find and clear error codes and check engine light yourself with a ELM-327 code reader and Torque lite on a smartphone for less than €8

The car has no power at high revs.
It is not going well.
The verification computer shows that the voltage supplied from the accelerator . But engines IACV do not drive.. We change all IACV but the probllem still same.
Monday will change the electrical coil on the accelerator , I think the problem is either there or in the cable itself . Before entering the workshop when my wife was driving I had a power loss , but fine after 100-200 meters , I think that something does not make good contact .
The worst that can be put computer is not working properly
