when i am at a light and have my foot on the brake. my engine idles at about 500 rpm then goes to about 800 up and down constantly till i go. i think there is a vacuum leak. there any way to test just the tubes? or do i need to use the vacumm test on all the vacuum lines? anyone else have that issue on the 5sfe.

It's not a vacuum leak.
Your idle will be higher if it was.
Could be a whole bunch of things
tuneup
fuel injection cleaning [or Seafoam]
clean ISC
EGR

my 7afes idle is very sensitive to the plugs being all gapped evenly. is the vibration rhythmic? if it is then check the gaps across all 4 plugs and make sure theyre evenly gapped.

I never thought to check the gaps. I didn't think that would make that much of a difference if they were noticably off. I'm checking this tomorrow just to make sure it's running as close to perfect as possible.

when one or more gap is larger/smaller than the others i get a rhythmic vibration from the engine when its at hot curb idle or in gear idle. i can usually tell how many plugs i need to regap and even guess the side of the engine from how it vibrates
but thats just me.

sometimes when my car is warmed up and sitting at idle my rpms will bounce from 850 and back to 500. I have been meaning to pull my plugs, but its good to know that it might be a gapping issue.
