Thanks sir, by the way sir I will ask another question. Is the cause of getting low idle when air conditioner is that there is no air conditioner amplifier? The air conditioner amplifier was not replace, instead they modified the the thermostat into a manual thermostat instead of electronic thermostat.

This could cause a problem because the system is designed to work one way and if they change it anything can happen.

Actually try cleaning throttle plate on both sides and iac hole with choke cleaner that may fix the idle but the low idle may be just the extra load that it places on the engine due to being a small engine.

I already clean the throttle body sir, already check the vsv and iac valve and all the hoses, its all okay. The mechanic also advice me that to put it back the air conditioner amp. Because he said there is no signal came from the air conditioner amp to the ecm. To make the idle up when ac is on, may hes right sir? On my day off I will do may best to connect the air conditioner amp. And I will massage you sir right away if may works will be okay. Thanks very much for the diagram.

Based on the formatting requirements of the website, I had to break this up into parts. I am attaching 6 closer views of the same diagram from above. Let us know if you need more info. Thanks.

Unfortunately, the manual does not give me the part number for this model year.

The best bet is to access the part and it should have a part number on it. Or you would have to call the dealer and they can check the VIN and pull the part number.
