vibration at redlight???
just tryin to track this one issue.
while I'm at stop light, brake on. I feel small vibration. it stops after I depress the brake and go.
it's only happening while I'm in D and brake pressed, won't happen anyother time.
it gets little annoyed when I have a/c on it's bit more.
and I've search through etc.
maybe motor munts? or I read this about breather hose.

RE: vibration at redlight???
I'm no mechanic, but it sounds light mis-firingplugs. I got this statement from a "Astro-Snot", by the name of JRL. Get the code reader and save yourself sometime.
I replaced the plugs in my "Ole tmr", from Bousch to Denso and the next day I was driving out of the PL, and I noticed that my idle was alittle rough. I am just trying to get on the Beltway, and break north!
But my car sounded rough and was riding like it wanted to call "Earrrrrrrl". Any way got Thee Pit Guy to check the codes, and I had fried to Ignition Coils 1&3, replaced them and about a week later 2,4&5 went.
Forgot to mention that when I would put on the brakes behind someone in traffic, the car acted like it wanted to run up in someone. Good luck.
That is my time... Thank you... God bless...

if its that type of vibration and only happens at idle then it has to be and engine/transmission mount and since there is no fault codes it makes it harder to diagnose ( you might want to check all the belts to see if anything is wobbling like a pulley )
