Hi all, how can I identify all the air hoses in the T series engine, whether these be larger hoses or thinner black tubes?

I still have a slightly wandering idle issue and when I was chatting with a mechanic, he suggested there could be a small air leak.

So I was thinking of changing what I needed to, but didn’t want to get confused with other hoses, eg coolant hoses!!

Hello, good afternoon, I wanted to ask you a long time ago.
Did you solve the unstable idle?
I have the same problem.
It goes up low sometimes it stops it has me crazy
I wait for your answer

Yes I did. I cleaned the throttle body and vacuum hoses with carb cleaner.

I also found a small part on the back of manifold that should have been blanked off, but the small plastic. Cap had perished. I taped it up instead. )I will take a picture of the area and post, but next week as I am on holiday at the moment).

All these things resolved the issue.

Hello good morning, thank you very much for your quick response, I hope those pictures.
Greetings good holiday.

Check the back of the throttle body, there is s cap that sits over one of the pipes. If not there, that is your air leak.

Hello good night, I have verified what you told me and the tube that goes to the ECU is connected.
Another tube that is connected to a pump can be?
and another exit that has a cap on,
In principle I think it's fine.
Also clean the acceleration body.
I have changed the idle sensor.
Also change the coolant temperature sensor.
Try adjusting the air inlet with the screw that has the acceleration body.
and finally adjust the throttle cable.
I have noticed some improvement but I still notice something unstable.
thanks greetings
Pd: how can I upload pictures?

thank you very much I will try to upload photos to the forum

Good evening I think I have done well I hope .......... Here I leave some pictures of my jewel with 25 years.
