vacuum leak?

[GraffitiPanda]

so my engine made a very low idle tonight when i cranked it... much like if i undo one of my vacuum plugs... so its only $40 for all new vacuum hoses... anyone els ever have this problem?

Mine will do it every once and a while. Try cleaning the ISC/IAC valve. Having said that, for $40, go ahead and replace all of them.

Did it go away or did it happen and is now staying?

it went away.. weird... but im replacing them still... i want to replace whats needed soon.

Good luck with the vacuum leak, Ive had my fair share of those by owning a 70's efi car I feel your pain bro.
