1989 Integra LS

How does one test for vacuum leaks - to see if they exist and where?

 

Must you test each line by disconnecting and using a vacuum meter of some kind? Do you listen very carefully? Do you spray a magically powder and look for something?

 

Any help?

 

You can spray carb or intake cleaner on the lines, start the engine and look for bubbles. This is not the proper method to use, though. Buy a vacum gauge and read the instructions, consult your helms or haynes.

What are the symptoms of the alledged vacum leak?

 

Symptions: rough idle. Don't know if it is an idle leak or not.

 

AFAIK, the only way you can test for a leak is a vacuum gauge. If you have a reason to think the lines are bad, replace them. Rubber vac hose costs pennies, or if you prefer, you can buy silicone hose in your choice of color that will last longer than the car, for example from Hose Techniques

 

+1 -- Vac hose is cheap! Do a search on IACV or FITV. If inconsistent idle is your only symptom, you need to try and narrow it down better. Could also need all the general tune up stuff. Plugs, Dist. Cap, Rotor, etc.

 

IACV or FITV seems not to exist on this model.

Yes, a tune-up was just performed.

 

I have question I washed the engine to my 93 acura integra and I got the distribator wt so I repaced my plugs a new distribator cap and now I wondering if I should replace the plug wires too or if its a vacum hose problem the problem is when I ma going down the road it acts like it don't want to take the gas then all of a sudden it will take the gas plus when I am at dead stop and the clutch in the rpms idle low and then back up to normal the back down what could be the cause of this

 

Yes, replace the plug wires!!! I had the same problem some years ago and I did a tune-up that included the upgrade in wire. Problem went away.
