T Series Air Hoses

#1 Post by Paul_1978_yorks » Thu Jan 11, 2018 11:01 pm

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!!

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.

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?
