Have you check your MAP sensor lately?
 

Hey guys and gals!


A few months ago I removed my stock intake piping and installed a WAI, which, I'm still getting around to making a CAI. Anyways, I was looking around the throttle body when I noticed the MAP sensor. Of course, it needs a solid vacuum line to do its job properly. Found and traced the vacuum line and was not very happy...



A new piece of vacuum line and a quick spray of soapy water to verify the line was good and!....no difference in engine responsiveness at all. Still, its good to know my baby is getting the right readings ;)


Cheers!

Very common. Every LD9 I've seen has this hose disintegrating.

I found the same problem with mine. Where are the other vacuum lines located that we need to look for?

That's the only one. the rest are hard plastic
