if you can see my previous threads, you can see that i had a problem with my car dying on stoplights, stops, etc....well i had always heard a damn whistling noise coming from my engine bay, it would always irritate me...well i went though the whole end if all idle problems thread, and did the fitv adjustment, iacv cleaning with no results, then i thought if the manifold and lines going through it have all the vacuum replacing the gaskets + lines should get rid of it theoreticaly, well i did replace the iab gaskets and the vacuum lines with no results, so then i looked through all the youtube videos and tried using soapy water inside a spraying bottle and i would affect the idle but it was because the iab gaskets would start absorbing the soapy water from so much i was spraying, well one day i looked at my brake booster lines and started spraying them with no result, so i followed them and accidently sprayed the master cylinder, and i heard the sucking noise so i put my hand around the cylinder and was able to affect the pitch of the vacuum, and there you go, i bought myself a new seal rod gasket at honda, because autozone did not carry it, and now i feel my car a lot smoother and has a better pickup as well, so fellow luders don't disregard this seal as a possible vacuum leak source, I HAD TWO YEARS WITH THIS DAMN VACUUM LEAK, hopefully this can help someone else with vacuum leaks in the future

 

congrats on getting your problem fixed. its always complicated with vacuum stuff

 

x2 good work. Some probs can be so hard to solve.
