Rough idle in drive but only when sitting at a stoplight

also turn off your climate control.. mine behaves exactly like this any time the AC is switched on (heating or cooling), whether the compressor is on or not.

i was actually just starting to wonder about the brake booster after reading your post the first time (couldnt respond from work) so thats my next step to curing the problem.

You know I tried turning off climate control on the way home, and it did seem to help. I'm going to test that theory more tomorrow morning before I pull the fuses. Figure I can get a baseline for climate control off but ABS (fuse anyway) on, then test climate on/off with the fuse pulled.

If it is HVAC related, anybody got a suggestion? It's a vacuum issue then I guess?
