little help please vacuum leak
i know i have a vacuum leak on my car it seem to be coming from around the intake area an it sounds big i can hear it from the drivers seat an the car wont idle itself you have to hold on the gas to keep it runnin. The question i have is does anybody here have an idea of what hose it could be i cant find it altho as loud as it sounds it seems like i should easyily be able to find it. But i been lookin all day with no luck. an i really think its a big one to sound like this.

You should be able to feel/hear a big one like that. It could be anything, from a bad manifold gasket to unseated air funnel to cracked or disconnected vacuum tube. This is one you pretty much have to do on your own, just do the ol' spray method.

Have you sprayed carb cleaner around to see if the idle changes? If you have and didn't find anything, then there is a good possibility that its under the UIM. There are a couple vac lines there that you can't get very well by spraying stuff, plus they don't always get checked and replaced like the others. I had a bad vac leak I could never find and it turned out to be one of the ones thet connects to the TB where goes under the UIM.

Upper Intake Manifold...it's the next big piece you get to after you remove the throttle body. My guess is that you probably have a worn out or torn gasket at the UIM or maybe the LIM. Replace those gaskets and add a bit of RTV. Make sure the mating surface betweet the parts is solidly sealed.

My guess is there's not much difference, but I have no way to tell you for sure. I've heard the HKS filters are either easier or harder to clean, but I can't remember which it is. Hopefully someone with more HKS experience can help you; I have the RX7.com Bönez filter myself.
