Before I start ripping things apart under the hood, are there any short cuts for tracking down leaks???

Click and Clack the Tappet Brothers use propane, waft it around the vacuum lines and somewhere you get an increase in revs. There be your leak. :lol:

If they haven't been replaced it's certainly not a bad idea. Just replace one at a time. Make sure you can figure out where each end is at and pull it off and pop on a new one.

Typically the ones on the top of the engine fail first. Typically, a vacuum line fail will eventually get bad enough that it will trigger a fuel trim related diagnostic trouble code. At least that's what happened on my AEB. The small vacuum hose can be purchased for relatively cheap. I recommend staying away from the fabric braided OEM stuff. It is too expensive and it doesn't last long, especially in dry/hot environments. I had to replace my first set of 3mm vacuum lines at the two year mark. I've got silicone hose on there now.

Deleted, because it was a bad idea.

Soapy water. Spray it on and it should bubble where the leak it.

Is it OK to suck soapy water in the vacumn lines?

Thanks for catching that. I was thinking backwards, and thinking pressure, not vacuum.

If your car is out of warranty, just start replacing the stock braided vaccum lines (if that is what you have). You could spend a lot of time and aggrevation on diagnostics, but vaccum line is cheap, and you are going to need to do it sooner or later anyway.

A forum search should turn up several sources for quality line.

how hard is it to replace all of the lines, do i have to remove a lot of stuff?
